I remember thinking the same thing when I got mine. I'd recommend not trying manual uninstall. it's a million little steps, all of which can be screwed up. a new rom is a lil scary at first but solves everything in one step.
this us what I would do if I'd just gotten the phone:
backup contacts and messages with pimbackup
connect to pc with usb (pc should have internet)
get task29 (version with boot screen, post 9 in this thread:
http://forum.ppcgeeks.com/showthread.php?t=116571 )
task 29 wipes your phone clean so that the new rom won't have problems. once you run it from
the pc you're committed cuz the phone is totally erased.
this is the rom I'd recommend, cleaned of all junk. run from pc after task 29. password is mightyrom.com .

run the provisioning program built in to the rom. needed to set the phone up with certain sprint only settings. also get this attached cab to bring back sprint's internet fixer setting (update user profile). you may never need it.
bring up some tutorials on rom flashing in case I missed anything, but it's easy. you can get the stock rom that you're currently using off htc website if you wanna go back.
