Frames up to your on own personal choice really, depending on riding style.
Wheels wise, majority of people are running pro2's, just because there dam good hubs.
Rims, well anything 24 really, personally I like sun's Rhyno lites, light and strong.
Forks, inspired? Seem to be getting rave reviews, but again depends on the frame really.
Bar and stem, something highrise probably, but again depends on frame and how you want the bike to feel. Maybe the trialtech high-rise's.
Hope this helps a bit.
