So far, I've noticed some drivability quirks. It hesitates a bit from just off-idle, and then kicks in with a good neck-jerking acceleration. I have a new accelerator pump installed, but maybe have to go after the whole carb rebuild. I often get unintended "one-wheel peals" in both first and second gear. I'd like it to be smoother.

Check the distributor vacuum advance unit for a leaking diaphragm. The effect of such leak might not be so significant WRT the advance curve, but the vacuum supply for that unit is ported at the carb. That is, cracking the throttle open may introduce enough of an air leak to affect the air-fuel ratio, resulting in flat spot.

The brakes engage with little pedal effort, but at times there is a nasty screech that seems to come from the left front just as its coming to a stop. I'm thinking maybe a problem with an out-of-round drum? There's some pulsing and then it grabs. Most of the time, though, the stops are smooth and straight, so I don't know where to start to look for a solution.

Screeching could indicate a problem with linings. If not simply glazed, they could be worn to the point that a rivet or shoe is starting to come in contact with the drum. Grabbing could be the result of a fluid soaked lining, a sticking wheel cylinder, or even a problem with a brake hose.
