If it can be managed without too much trouble, run at least one dedicated line for your audio system. Two would be better, one for the audio, and one for the video. I ran one line, 10 gauge wire on a 20 amp breaker, that feeds two outlets. The outlet that has the bulk of the AV system has a PS Audio Soloist in-wall outlet. I have two amps on that circuit, a 300wpc Aragon two-channel, and an Adcom GFA 7400 5X100wpc amp, along with the bulk of the video, and some of the digital in that outlet. The remainder of the digital and the analog system is plugged into the other outlet, with a PS Audio Power Plant300 plugged into that. This has worked out well for me, but I think another dedicated circuit would be better.
This is a very inexpensive upgrade, and since you are involved in a remodel anyway, well worth the trouble and modest cost, especially if you can manage it yourself. By any means, now is the perfect time to get it done, you won't regret it, it's well worth it.
Best of luck,
