Hey grizzly,
While I am not a certified electrician, I did stay at a holiday inn express last night.........I would run 12-2 romex for my circuits, that way you could even go with a 20 amp breaker, if you went with 14-2 you could only go up to 15 amps I believe, and since your starting from scratch you might as well set it up for any "future proofing".Btw, I have six components, two speakers w/powered subs and a 46" crt rptv all plugged into a 15 amp breaker and have had no problems with it tripping.
