As requested:
There's a couple apps that will make this a lot easier. Titanium Backup and Quick Boot. Both are free in the market.
Obviously you need root to do this. Do a Google search for "Unrevoked" if you don't have root yet.
Next, read 9) Flashing Custom Roms in this thread: How 2 - ADB, Rooting(reflash), Unrooting, Nandroid, Remove/Install App, roms, kernels - xda-developers.
You don't need to do the ADB stuff. Just use Quick Boot to boot into recovery and select "Install zip from sdcard" then select the zip of the ROM you are installing.
That's it. Enjoy.
Here's the ROM I am currently using (crap, there's a new version I need to get):
[ROM] Incredibly Re-Engineered v2.3 [02-8-11] Fast, Beautiful, and Simply Magnificent - xda-developers
