Sounds Like a plan.

No, 36 could not handle the current. 24 or 26 gauge would be your best choice.

Probably 12-15kv -at- 60ma

A small TCBOR (RQ) type SG will give you great prformance increases, and
allow you to run your coil longer.

Neon sign wire will most likely work best at this low current level.

Should be OK, just remember to turn off your computer.
