I don't know for a fact what the venue's capacity is, but it is large .. maybe 2,000 (probably more) or so could fit in there, but for ideal band viewing maybe 750 - 1,000 might be the max. The floor level is fairly large, and the upper level has a catwalk that winds around two sides, and then a large area in which viewing wouldn't be too good. Someone correct me if they have exact figures or more knowledge than myself.
As for question #2 ... Kamelot/Epica recently had about 500 show up, and there was still plenty of room. I guess I'd say 750-1000 might be a good goal for CPF for this venue, and it might be possible to better those totals if the headliners have good drawing power. Maybe Chris or Rob can comment in this thread ?
