restoring itunes/iphone after format

My hard drive died yesterday and with it went all my itunes data as well as all my music and everything else to do with my iphone.

Can I just install a fresh copy of itunes and hit sync and it will copy all apps/music/videos/contacts/settings/etc... from the phone back into itunes?

If not, Is there any program that can backup the entire phone and reintegrate it back into itunes so that I can sync my phone normally?

Doesn't matter if it's a jailbroken app etc... I'm willing to use whatever is available
