Ozfly,
I won't comment on Albertporter's or AVDcreations' recommendations on what to do. From previous posts, Albertproter has a room envied by many AudiogoNers, past and present.
However, both Sean and Albertporter have good thoughts on HOW. It is way cheaper to do things now than to put in something that is only half of what you want with the plan to "make it right" later. Besides, you never will. Most of the construction improvements will cost hardly more than the material upgrades if planned for now. Things like 1-1/2" thick subflooring or conduits run through the slab will be prohibitively expensive or impossible if not done now.
Also, please listen to Albertporter when he suggests that you carefully supervise the plans. Supervise the construction closely, also. There will be plenty of places for a contractor to cut corners with the unusual specifications that a sound room like this wil have. From the new construction I've seen recently, contractors cut corners on normal stuff already. For example, if your final design calls for laminating three layers of sheet rock on all the walls, you'll have to make sure that the contractor uses glue between the layers. If he's not watched, chances are he won't.
I hope I haven't offended any members who are contractors. This has been my previous experience.
