I'm no old hand at the cloth room, but one tip I've heard from apparently able users, but have not seen mentioned in this thread is to think real-life when planning your animation, and the simulation will go easier.

Meaning if you want a complex sitting position in your final frame, do a couple of "partway" poses in the progress of the animation time line. This supposedly will help the software figure out how to get both figure and cloth get to the end position.

I haven't personally tried this, because at this point I haven't done anything really difficult, pose-wise, in the cloth-room. Perhaps someone else can verify.
