Beware that this version still seems to have the bug where initial wallet.dat creation does not fill the keypool with 100 pregenerated keypairs. Someone just lost a lot of BTC because of that (see
http://forum.bitcoin.org/index.php?topic=11104.0).
Actually that guy lost his coins before keypool was created, in fact, keypool was created as a response to that person's post.
That said, yes you are right, before you backup the first time, make sure you get some coins and/or send some.
