I might just try that. If I do, should I do it this way?
That's what I would do 
But you have moved the wallet.dat already now, so all you need to do is restart syncing.One thing I don't quite understand, I have a wallet but can't view my public key/receiving address at all, without downloading the entire history of the blockchain... If I had that info, I could just punch that into here? http://www.homebitcoin.com/easybalance/
