n00b with a 4BDA and P4 1.8a

I've read alot of the posts here on this forum about the EPoX board, and I love my 8KHA+. However, I've never played with a P4 until now. So I picked up a 4BDA and a 1.8A. I also picked up a 512MB stick of Corsair XMS PC3200. I obviously intend to O/C this sucker as much as I can. =) My question to you gurus is how should I go about O/C'ing this? I would love to hear about your experiences with this board, CPU, and hopefully with this RAM as well. I intend to get this sucker water-cooled eventually with one of the new swiftech kits, but want to know how far I can push this thing on air. Also, will I need to do any voltage mods or any other mods for that matter? Thanks alot!
