^^ That just about covers it.

I've made a few posts in threads like these detailing what programs/modifications etc I like, and I'm sure there's many others. First thing I did when I got mine was to do a lot of reading and browsing forums (this one and XDA-developers, even though they're not that omnia friendly, they do have some good info).

ps before flashing ROMs, make sure the phone has the latest CF03 update because you will not be able to do any flashing without it. start > settings > system > version I think is the way to get to the screen that tells you the ROM version. VZW and Samsung have an official update to bring you up to speed with that, and then for the "cooked" ROms all you need is a tool called UMDL and the .bin file. There's definitely no lack of instructions around here but feel free to ask.
