Make sure my offline Wallet is ok? Let's say I make an offline wallet from a live cd with bitcoins-qt.
I make some addresses (10 pcs.)
I encrypt the wallet. Save it on a usb (wallet.dat).
I then send over some bitcoins to one of my newly made ​​addresses.

Then I run my normal OS (online) and install bitcoins-qt, download the whole block chain.
Closes bitcoins-qt.
Replaces wallet.dat with my encrypted wallet.dat
Starts bitcoins-qt.

Can I see the balance of my addresses, without decrypting the wallet?
Is it once I'll send them as I have to decrypt it?

If this works ... Can I in any way try to decrypt the same wallet offline (without the block chain?) To ensure that I can access it, the day I'll send my bitcoins?

Is there a security risk with going online with my wallet.dat if I never decrypts it online?

Edit:
I know that I can see my balance online without the private key.
But I can't think of any other way to make 100% sure I can access my bitcoins in the future?
1.First I make sure that my wallet.dat is working and does have my adresses and the correct amount of bitcoins. (without decrypting it).
2.Then I go offline and make sure I can decrypt the exact same wallet.dat

Is this possible?
If you just want to check if your wallet/password is working, you can do so using the bigcoin-qt debug window. To open the window, select "Help" from the menu bar, and then "Debug Window". Once you open the debug window, you can type this:

walletpassphrase "your walletpassphrase here" 600


to unlock your wallet. If the command completes without an error, you wallet has been decrypted successfully. If you get an error, your wallet couldn't be decrypted. From that same console, you can type this:

listaddressgroupings


to see the addresses stored in the wallet. When you are finished, type this:

walletlock


to lock the wallet. You do not need to be on the internet to do this, so you could do it from your live cd. I also believe you can do this without having downloaded the block chain, but I haven't tested it so I'm not 100% sure. Additionally, the commands available from the debug window are listed here if there are other things you would like to check.
