Yes to both.
I'll double-check at work which way the copper galvanized works. I think
the galvanizing leaches into the copper exposing the bare steel to rust.
If you must place copper on galvanuizing, use a leaf of stainless steel
in-between to prevent contact. Also cover the joint with anti-oxident.
PolyPhaser makes both products. The anti-oxident is copper based.
No-Alox or equivalent will work too.

I have read that bare copper leaching onto galvanized
steel encourages rust. Can anyone confirm?
Wouldn't an aluminum wire be a better choice?
