But, while you are here...
There are no bitcoins in your wallet. Your wallet contains keys that can be used to redeem bitcoins that have been sent to you, and a cache of transaction data involving those keys.
1. When your node is fully synchronized with the network and has completed rescanning the blocks, you'll see 0.011 BTC. You may see 0.01 at first, or even zero, depending on what blocks have been seen by the node you are using the wallet on.
2. Normally, do a new load of the bitcoin software on a new computer, drop the backup wallet into the data directory, rename it to wallet.dat, start the node and let it sync up.
3. Depends how you feel about having your bitcoins stolen.
