Fireplace is tough. I wanted to do it but it was too much work. If it's a masonry fireplace like mine, you can't just run wire behind the drywall, there's a fireplace chimney there. You can mount the plasma on the masonry using the right screws, just not comfortable in making holes in the chimney myself. Some people build a false wall over the fireplace to mount the plasma display and run the wires through.
If you get past that problem, the best way is to have an electrician run a big 2"+ conduit so you can pull cables from the plasma to the stack of equipment at will. You don't want to rely on knowing in advance every cable you may need. You are saying DVI but the TV you got doesn't have DVI and what if the world goes to HDMI next year? What about a computer connection? To many what ifs, you need flexibility to change. Power is the easiest thing for an electrician to run and you should have an outlet right where the plasma is.
A few years back at CES the big thing was bluetooth enabled displays. Just plug it in the wall and the DVD, STB, and anything else connected via bluetooth. Don't know what happened but it apparently didn't make it to the stores. The big think last year was a couple of companies make very thin flat wire for component, power, DVi or anything you want. Basically you spray glue on the wall and cable and press it on. Put special terminals at the end for the connectors and smooth over it with drywall compound and spray texture on (if your walls are textured). Looked like a great idea, specially in your situation.
