Help I'm almost done with my 620 sf studio and need help...

Ok I would like to describe my new room and see what you guys might do for treatment. I tried to sketchup my room but just don't get it. So ok this is what I have 18' wide, 23' long and vaulted ceilings 10' that vaults to 14 1/2' There are two doors that swing inward and both are on the face of the building. (you can see pics on the gearslutz.com 'photos of studio building projects' under 'Ear Witness Studio build from scratch' thread) Now the console is going to be facing the long way so the 18' side and I have already put conduit running to the side walls. My question is about treatment to the room. It will have pergo floors and I would like to make a cloud that has absorption and lights built in but wondering on that size a room how much diffusion and absorption should be on the walls. My gear is PT HD Acell 2, C24 (coming) a couple of racks of pres, summing and comps, Dynaudio AIR15's on stands, and I'm thinking about sofit mounting some larger mains for showing off mixes to clients. I want a couch in the room too. Any advice, or can anywant do a quick sketch this up. If you want to see pics again they are already all on gearslutz but I'm not getting much help there. The pics are housed on my facebook and myspace so if you look up Sam Knaak you can add me and see all the photos. www.myspace.com/earwitness Any help/advice would be great. Sam
