It's not especially important to have all gaps *exactly* equal, but it will
be easier to fine tune if they are, because you'll be able to add/subtract
distance in small equal increments.

2kVA minimum (18 amps at 120 volts). But bigger is better, so get a
25amp/3kVA unit if you have a choice.

All the NST cases should connect to the same heavy RF ground as the safety
gap, the bottom of the secondary coil, the strike rail and anything else
that might get struck. So yes, the cases should be electrically connected
together, and _must_ be grounded.

Yes, you can add the current (ampere) ratings.
