What is the plan? Do a short or long wall setup? Will you be using this for 2ch listening or HT use as well?
If 'all new' construction, investigate audio oriented building materials and techniques. Staggering studs is a good idea to decouple inner and outer walls. Weaving a hi-density acoustic material BETWEEN the studs helps lots.
Pre wire? absolutely! 1 or 2 exclusive circuits and maybe even a sub panel for power. Cable TV? Pre wire that, too. Between the new listening room and the rest of the house, consider an Exterior door. Non-parellel walls/floor/ceiling are certainly a good idea to reduce standing wave propagation. Taper all walls differently. I have seen a recording studio made with this in mind.
Windows? Double glazed vinyl probably. Low -E-. If designing for HT, place appropriately and consider where the sun would come in.
Think about where you intend to sit and HOW MANY people. It is a bad idea to sit mid-way of any dimension. I Personally don't like sitting up against walls, but I have seen some advocates of that position.
The dimensions you have chosen are 'perfect' golden section numbers. My plans are similiar except I added a 2'deep by 7' wide by 5'high 'alcove' for the placement of a RPTV since I intend to ultimately have a 5.1 HT oriented system. I was planning a long-wall setup, with the listeners about 3 feet or so from the BACK wall, leaving an isle and providing some ambient space.
Also, please consider BOOK SHELVES as both a design and acoustic element.
