Thanks for all the helpful info - this list is great! :)

So far I understand the following:  assuming I have separate ckts for 
the studio, it doesn't matter which "phase" they are on (which side of 
the panel).  So far so good.

Now this is a little more complicated.

Ok, I have one twisted copper ground wire from my panel to the city 
side of my water line, and another similar copper wire (from the panel) 
connected to a rod buried in the ground just under the service 
entrance.  Does this count as one common ground point?

And the thing to do here would be to disconnect the neutral ground and 
connect signal ground to earth ground, yes?

And as for MOVs - those are the cheap surge protection devices in yer 
typical plug strip?  What exactly is the problem with these?  My whole 
studio is infested with them! :(

Thanks again,
