Looking great! I just finished a shoestring conversion of my basement room into a theater and here's my 2cents. Dont skimp on pulling wires to locations that will be inaccessible after you finish. The cost of the wiring/cable, etc. is realtively cheap (monoprice.com) so overestimate. Maybe buy a roll or Cat 6 wire and run 4-5 of it everywhere. Sounds like overkill i am sure but its very cheap and may save messiness later on.
Also, the more indirect the lighting the better. I have a cove light (rope light hidden in a molding) running around the room and it made the room. I think yo uare doing that too.
Keep it up! Get ready for the first movie you want to watch....
