Just rooted my HTC Evo using unrevoked.com need help with a ROM

[nickg88]

so i finally just figured out how to root my phone..so now that i have it rooted im not really sure wat to do? i know i want to install some kind of custom ROM to be able to do the things i wanna do like get free apps, overclock n underclock, wireless tethering, complete customization, things of that sort.. but the problem is i have no clue where to start since im very new to this and unexperienced.. so if somebody could point me in the right directions and throw me a few suggestions it would be greatly appreciated
