I dropped by Mike's shop yesterday to evaluate the clutch situation, again. I don't find any leaks at the slave cylinder, but didn't check the back of the master cylinder. I did a gravity bleed on the system, again, and immediately, there were air bubbles coming out the bleeder. It's very possible that I didn't get everything out in previous attempts. Only time will tell, once we get it back up and running and the clutch is in use again.
Side note: Northlake Automotive is beginning to look a little like The Fiero Factory, Jr. with the 88 Formula Fastback, the 88 Coupe 3800SC and the 86 SE.
