I suggest you play around with the software and the basic operations of the phone for a day or so. Try everything to get used to how it works. Then do a clear storage/hard reset to start fresh and then begin modding your device. Research about available mods before you start changeing things. Read, Read, Read, and really understand what you are doing before you jump in. You'll be much happier with your device if you do what I suggest. Good Luck!
FYI: Boxwave makes a great soft protective case. You can run Android on your TP2 regardless of your carrier or phone package/plan.
