I use RJ45 to DB-x connectors for my server connections, and some 
recommend _not_ using twisted pair for RS232 because it can introduce 
crosstalk that untwisted cables wouldn't.  I have no idea if this is 
true for RS232 or extending a mic/control head.

For 3', I don't think it would matter.

I used a flat 8 conductor phone cable to extend my D700 mic cable.

I think I saw some STP at www.bgmicro.com once upon a time.  I can't 
remember the length.
