To close two outstanding issues...

Bad temp sender was the source of the alleged overheating problem. Gauge 
said hot, actual temp was normal.

...and I did indeed have a plugged drain causing intermittent dripping 
into the passenger compartment. I had checked the drains and the left 
side ran fine...guess the right side didn't. :)
