The only advice I can really offer is try visiting
http://www.ngemu.com , oh, and wait ^_^
PS2 emulation is really in the early stages, a few games boot, but not really playable. A new release of one of the best emu's, PCSX2, is supposed to be happening around November 25th though, so we'll see then :-)
I guess other advice is check you've got the latest plugins, and just experiment shed loads with all the different settings. Thats how I got PS emulation to work :-)
Hope it helps.
