Congrats on the TP2 purchase....I'm really enjoying mine (Verizon also). I was very hesitant to flash a custom rom, but bit the bullet. Holy crap are the custom roms superior in speed and user interface experience.
If you want to stay stock, you may want to hard reset (clear storage in the memory option of settings). See if that speeds things up (note that it will clear all of your settings).
If you feel you'd like to take the plunge and flash a custom rom, I'd suggest MightyROM as it's 2.5 and he keeps it really bare bones and like stock. You'll need to reed how to unlock the phone first (HSPL)....read here COMPLETELY

Then read the first couple of pages of Mighty's ROM here...

Don't hesitate to ask questions, and even PM me if you'd like some help!
Good luck with your new new ppc!
