Thanks for your suggestions.  I was successful fixing both problems.

The lamp socket was blocked by the rubber insulation on the wires.  Using the heat gun, the rubber softened enough to fall apart and I could push the lamp out of the socket.

A spot or two of oil and a large pair of pliers to pry off the clip did the job on the plastic dial and no damage.

I am a happy camper and can proceed with cleaning and repairing the chassis.
