Auggh...take off the caps lock!
Seriously, welcome to the Boards, Jim. I loved Thailand. When in Bangkok, you can get around quite a bit using the Chao Praya River Express. It's basically a river bus that stops all along at different points. The stops are very convenient for the temples and such. You can also hire a tuk-tuk for the day, and have him take you around to see what you want to.
As for day trips out of Bangkok, I thought Ayyuthaya was awesome, and another friend liked Lopburi. Lots of cool ruined temples from Thailand's medieval days...
