I did a test start on the engine today. Ran smoothly at 760 rpm on the EI. I didn't have a helper, and the mag was not running well after being overhauled, so I did not do the timing. My question is what rpm is best to do the timing at? Can it be accomplished at idle, or should another range be used?

I like to use 1000 rpm. Set that range to a value you have marked on your flywheel 10/ 25 etc. Make sure rpm reads 1000 in gauge mode.

Shoot it with the gun and set Magnet Position so mark coincides with your timing entered.

Default is 90 on a Lycoming. With single pickups we usually see 89-91, dual picks around 86 on one and 93 on the other.
