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. :)
