Update: Retrieving coins

Alright here's where I'm at. I have the wallet.dat file, and I have a file labeled multibit.key (which I'm assuming has to do with bitcoin, not doge). I didn't have the Dogecoin-QT app on my computer anymore but I did have a backup of my computer so I restored the app and now have it open but it is not syncing. According to the ELI5 that doesn't matter though. It says in recent transactions I tried to send out all of my doge to my reddit account but since it wasn't synced I don't know if that went through (although balance says 0). I tried using the help-debug-console where you do dumpprivkey "address" and it says that "Private key for address 'address' is not known (code -4)". I forgot to unlock before trying to get the private key. I now have my private key, but when I try to import to MultiDoge it wants a file instead of pasting the private key in. Would anyone know where to go from here? I used dogechain to import private key and it now shows full balance. I think I did it? Yep, I did it. Keeping the post up for future searches, hopefully it helps someone else.
Side question: Since the old dogetipbot is gone I can no longer access history or balance, what happened to the doge I had in that account? Is there a way I can access it?

Importing Private keys into a QT based wallet, how is it done?

Before the fork I had been storing my tokens in MultiBit. I saw no need to incur a transaction fee to transfer those tokens into a QT compatible wallet format prior to the fork. So now I am here with multiple files that contain the private key(s) from those wallets.
I now need to import these keys into both my Bitcoin (Cash) and Bitcoin (Settlement) QT clients. What are the steps necessary to accomplish this?
I did find https://bitcointalk.org/index.php?topic=336404.0
Is this a safe method in which to perform the activity? I will be importing to Bitcoin ABC v0.14.6 & Bitcoin Unlimited v1.0.3.0
  1. Export private key from MultiBit without password (Done)
  2. edit file with some editor like Notepad++ (I'll probably just use Notepad, unless that is a bad idea?)
  3. copy only key - this is row without # ,and you must copy only key - no date and another symbols , (row indicates that it might be better to import to a spreadsheet?)
  4. then in BitCoin-Qt open from Help->Debug window ->Console (I am able to navigate to where the Console is not located)
  5. importprivkey [label] [rescan=true]
(Where is the information I copied from step 3? and also without the '<>')
(where label is name of owner - your name.; is this necessary? Do I need to provide a label? Can I leave it blank? And if I can leave it blank would I simply omit that the '[label]' argument?)
  1. And when press enter the your address with coins will appear in your addresses and in your balance.
Additionally, can this activity take place on a computer that is not connected to the applicable network? I am still waiting (1 year 40 weeks behind) for the Bitcoin (Settlement) wallet to download the chain (for some reason copying over of the pre-fork blocks did not take and now that the fork has occurred I do not want to try to start over or run the risk of re-installing).
Thank you for your assistance.

[Guide] How to transfer your wallet from your computer to android.

I got tired of waiting and waiting for the whole blockchain to sync so I decided to move my dogecoins to my phone since the app does not need to download the whole chain. (Luckily there is a bounty for a electrum equivalent that will hopefully arrive soon.)
It is much much easier if you just transfer some funds to a new address on your android phone, but this tutorial is for those people like me who can't even get the dogecoin app to sync.
Surprisingly the whole process was very simple. Don't be put off by all the text or all the talk about security. I just want things to be accessible to beginners and to practice good habits. Root is not required.
Note: I am assuming you are using the official dogecoin-qt app and the Dogecoin Wallet app by langerhans.
Disclaimer: This will involve having your private key stored in plaintext. Proceed with caution and treat that file like you would a password. Do not share your private key with anyone.

Getting your private keys

A wallet comprises of public keys and private keys. Public keys are the addresses that you share, you can only use them for viewing. Private keys let you actually make transfers and are what makes you the owner of the wallet. Today we will be transferring those private keys to your phone. They will still be present on your computer unless you delete them, so keep that in mind security-wise.
You will have to replace everything in '<>' with your own values.
  1. Open the desktop app
  2. Open the wallet console by going to: Help -> Debug Window -> Console
  3. If your wallet is locked with a password, you'll need to unlock it by typing: "walletpassphrase 120".
  4. Get the private key for an address by typing: "dumpprivkey "
  5. Save the private key to a file.
  6. Repeat this for each address that you want to transfer over.
Please think about how much dogecoins you want to transfer over. Brarsh:
Do you need that much? What if you lose your device? Just like only keeping a small amount of cash in your wallet and most safe in the bank, only carry what you could conceivably use for that time without access to your main wallet.

Creating a backup file

Next we need to create a backup file so that we can import our addresses into the android app. The android app uses the same format for its backup files as MultiBit (A popular bitcoin app). A typical file looks like the following:
# KEEP YOUR PRIVATE KEYS SAFE! Anyone who can read this can spend your Bitcoins. Kwmxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2013-06-22T18:36:35Z L1Sxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2013-05-04T22:47:32Z Kxwxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2013-05-08T00:58:28Z 
What we want to do is put our private keys in the following format: key date-of-address-creation, where the date is in the format YYYY-MM-DDTHH:MM:SSZ. Note the T and the Z. The android app needs the date so it knows how far back into the blockchain it needs to sync.
If you can't remember when you created the address, visit http://dogechain.info/address/YOURADDRESS and get the date of the earliest transaction. It says that the dates are approximate, so I'd just put 00:00:00 for the time.
You should now have a valid unencrypted backup of your wallet.

Importing the backup

  1. Transfer the backup to your android phone, placing it in your Download folder. It has to be put in the Download folder or else the dogecoin app won't find the backup. Make sure it has a name you'll remember later.
  2. Open the dogecoin app and click on: Back Up Keys -> Restore private keys. Click on the name of the backup and from the list that shows up, look for your backup, which should be unencrypted. Click Restore.
  3. Delete the backup in your Downloads folder. Remember, your private key is stored in plaintext in there, so it is important that you delete it. Delete the backup on your computer if it is there also.
  4. Wait for the app to sync completely. Your addresses will be added to the addresses that were already in the app, and your transactions should show up. If they do not, make sure that the date you put was correct and early enough.
  5. Go to Back up Keys > Back up private keys and create a backup. This time it will be encrypted with a password :). If you do not have a backup, you could lose all your coins if you lose your phone or the data on it.
  6. To the moon!

Terminology

I just got into dogecoin two days ago so correct me if any of this is wrong. Same thing with anything in the post :).
Blockchain/Dogechain: The blockchain is a ledger (record) of all the dogecoin transactions that have ever taken place. As of writing it is larger than 1GB in size. The blockchain is needed to find out how many funds you have in your wallet.
Wallet: A wallet is the digital equivalent of a real life wallet. It is where your money is tied to (It doesn't contain actual dogecoins, but someone else could explain that better than me). The wallet contains your addresses and your private keys, both which are needed to receive and send dogecoins respectively.
