This is just a random guess but out of all those extra things you installed, did you install the tweak to keep WiFi on when the phone is in standby? Having the WiFi on like that can really kill the battery.

The other usual suspect is your signal strength and whether your phone is entering analog roam (can the TP2 do analog? I've only had mine for a couple days). So, if you can, try to keep your phone in an area with good coverage. With my old Vogue leaving the phone on my belt would kill it within a couple hours at work, whereas leaving it on my desk about three feet away (closer to the window, I'm in a basement) had the battery at 70% at the end of the day.
