Use File>Transfer Purchases in iTunes to get the paid music and applications off the phone. (Applications can be re-downloaded for free anyhow; music cannot)
There's a section in this article that tells you what's saved in a backup:
And should help you figure out what you want to grab manually, or what is already covered by sync, duplicated from your computer, etc.
There are some third-party utilities--use at own risk, not supported by Apple--that pull stuff off the phone, if necessary---google PhoneView, TouchCopy.
