To be safe for future cabling needs, think about running Cat5e or Cat6 along with the video cables. If there's a chance that you'll want to use a distributed audio system that uses keypads, run Cat5e with the 4 conductor speaker wire and leave a loop in a location that would be a convenient place for a volume control. If this isn't going to happen, don't worry about it. If you have a basement with space for running cables above the ceiling (or if it's exposed joists/unfinished), make sure that whatever hole(s) you drill in the wall/floor are big enough for the wires AND plugs to fit if you need to add something later.
