Just to be straight on this. do you mean render passes as in spec/shadow/reflection/ambient etc, or passes as in everything rendered at once just at , well, actually i guess a combination of both would work wouldnt it.
as far as compositing. I only use photoshop. No toxic or any of those other plug "channel 'x' into channel'y' " type ones. Im happy playing about with blending modes and opacity levels and whatnot. My main idea I guess is to just try and get a bunch of renders together that i can clone tool out of one and into another, but I doubt thats what you mean by compositing skills!
I watched a digital tutors render layers tut last night,, but it was maya 2009, using tokens, and contribution maps (which looked like just what i might need), and render 'passes' of seperate render 'layers'. But as ive got 2008 it wasnt really that helpful.
