dedicated curcuit question????

I am in the process of having an electrician friend run a dedicated curcuit to my HT-2 channel system.I currently have 2 seperate systems in the same rack.My 2 channel(power amp,cd player,preamp,DAC.My HT system consists of an AV reciever,DVD player,5 channel amp,vcr,cable box and a 36 inch TV.I have most of my gear plugged into a power conditioner,surge protector(Monster Cable HTS 5000) My question is: I can run whatever I want everything is very accesible(its in my basement) Should I run 2 seperate lines from 2 dedicated curcuits? Should I use a 20 amp breaker? What about an isolated ground? I was going to use the PS Audio power ports for outlets.Are these worth 50 bucks apiece or is it overkill? I would greatly appreciate any advice?
