[sdiy] Isolation transformer question..

Alrighty, so I want to put all the gear in my studio on a transformer
to isolate it from the rest of the mains in my house..and preferably
each other. Just wanted to run this by everybody in case there's
something I'm not thinking of:

I'm using a super-duper medical-grade transformer I found discarded
somewhere. 5KVA, .005pf capacitance (which is supposed to be very good
isolation from what I've read). I've wired the primary windings in parallel
for 120V input and have two separate windings each of 120V on the
secondary. The idea is to have one circuit coming from each secondary
winding, one with audio gear on it, the other with computers/TV/video
gear/anything with a motor/non-audio on it, so as to reduce noise.

Is this likely to help with computer-related switcher noise?
