SetCPU, Wired and WiFI tethering apps from my signature (even if you never intend to use them better that you have them than need them and can't find them), Titanium Backup, Terminal Emulator, and an immediate Nandroid backup just in case you hate whatever ROM you end up flashing because you get bored with stock. Trust me, ANY of the AOSP ROMs and most if not all of the hacked ROMs are better than stock.
