Issue is finally resolved. Pulled the trans back out and re-torqued the pressure plate. Turns out I babied those bolts since I didn't have a torque wrench and they were not tightened enough and the pressure plate was not clamped all the way down against the flywheel which I guess gave me too little pre-load on the clutch spring. Anyway, picked up a correctly rated torque wrench, torqued the bolts all to spec, put everything back together and now the clutch engagement point is like 3" off the floor instead of on the floor. Hopefully my auto parts store parts hold up and I don't have to pull that trans again for some time.
