Exported a private key from bitcoin-qt to omniwallet.org and now the wallet within omniwallet.org says $0.00 when I know for a fact that there is bitcoin on that wallet. /r/Bitcoin

What's the best way to export private keys from an old Bitcoin QT wallet

I have a backup of an old Bitcoin QT wallet (from 2013-ish). I know the wallet is empty, but I would still like to have a few of the private keys from it (to be able to prove that I was in possession of bitcoins at this time).
What is the best way to export a few private keys from the wallet? I'd rather not download the entire blockchain just to export a few keys.

Bitcoin QT keeps crashing on Mac. How do I export my Wallet?

I want to export my wallet and open on a Linux machine. Armory and Bitcoin-QT keep crashing -- I just updated them last week and I'm concerned I won't be able to access my coins.

Trying to export my wallet.dat from Bitcoin-Qt, but one of the receiving addresses (and its private key) seems to have disappeared. What to do?

I'm trying to move from Bitcoin-Qt to MultiBit. After upgrading Bitcoin-Qt to 0.8.1 from 0.7.x (supposedly mandatory upgrade/fix because of Bitcoin protocol issues), it always tells me that the block chain is corrupt and I need to rebuild it. Tried a bunch of things, it still does it whenever I start. This easily takes over a day and I want something more lightweight on my laptop anyway, so I switch to MultiBit.
Got pretty much all my BTC out of my old wallet, but I still want to import the existing private keys and (if possible) transaction records. As I understand, I need to get the keys from wallet.dat in json format, and import them into MultiBit. Should be easy enough, no?
First, I tried taking the output of pywallet and importing it into MultiBit. I choose the file, click the button to import, and it does nothing. (The wallet is several megabytes with lots of txns, so it might not have been prepared to handle that big of a file.) Of course I later learn that I'm supposed to just import the private keys, but pywallet doesn't appear to have an option for that?
So I go to Blockchain.info, and (hesitantly) created a wallet there with my wallet.dat. It works, but the balance is short of what it should be. Since then I sent nearly all of my balance via Bitcoin-Qt with no problem, but my balance right now is 0.0004 in Blockchain
