The dirty truth - all my stuff is plugged into a 6-gang and into the wall... on a shared 15 amp circuit - the only thing I did when we moved it was remove the dimmers from the lights.
I know you want to do the best by your equipment and go "the extra step"... but it's probably unnecessary.
Although on This Old House, they did show how to save energy by putting your A/V equipment on a power bar - the draw on "standby" electronics was actually fairly high. The frustration of resetting clocks and timers and resetting your TV picture every time you turn them on is probably greater.
