If you're going to use a power conditioner, why wouldn't you just plug everything into it? Most of them have eight or more outlets, and you can plug another power strip into one or more of those, so as long as you are minding the total current draw, plug it all in! Why would stereo rigs make a difference?
I guess if I try to analyze a bit further, some of my pedals and older, more poorly-designed rack gear are susceptible to noisy power. So they are the only units that I "need" to plug into a conditioner. All the modern rack gear has its own line regulation and filtering built in.
As much as I can. All my stuff, all the guitarists stuff if the stage is cramped. A fan for the drummer. My cell phone charge. My laptop charger. Ipod charger.
