What do I need to do different in terms of wiring the speakers or cat5e to this room so I can either run it locally or distribute it from the main location?
Make sure you are using the right coax. RG6 with copper-clad steel center conductor and aluminum braid is not it. It may work for a short distance, I just wouldn't use it in a new construction.
What you need is bare copper center conductor, 100% aluminum foil shield and 95% tinned copper braid. You probably don't need RG6, however. Depending on your distances, Mini coax or RG59 would probably suffice. Also, what are you doing for audio? If you want to distribute 7.1 audio, you need at least another coax (of same construction) for coaxial digital out. If all you have is optical toslink, you will need some sort of converter from coax or Cat 5e. Make sure you are also running enough wire for IR return - unless you are doing a whole-house RF solution.
As with Roddy, check some of my previous posts on coax. This is a subject that comes up quite often.
