Thad-
I saw that you tried to PM me today, but my mailbox was full. It's empty now.
Phantom-
Just FYI, what I had you do was verify that the coil received power when you turned the key on. That eliminates your entire wiring system as suspect, and focuses on the coil itself, the distributor, or the wires. The second part of the test you did, where the light flickered, ruled out the distributor internals, and the trigger that tells the coil when to fire. That left the cap and rotor and the wires. It sounds like there was either too much build up on the contacts, or you had a coil wire loose at the cap. Either way, I'd replace the cap and rotor with your next paycheck. If you do, buy a cap and rotor with brass contacts. They cost a few bucks more, but they virtually eliminate the kind of problem you had from happening again. As far as an ignition box, I still stand by my first recommendation: Crane HI-6.
Take care,
