Do you need to re-balance the crank, etc. if you go from an OEM to SuperMiata Crank pulley?

As far as I know the crank is balanced without the crank pulley as the crank pulley is supposed to be a balanced unit on its own. You should not have an issue.

I've never heard of any shop balancing a crank with the harmonic damper installer.

Seems to me that damping vibration is the last thing you'd want to happen while something is on the spin balancer.

No, you'll be fine. Miata engines are internally balanced.
