You're joking, right?

My main questions for those who have experience with such things, a
1. What do I look for to find the switch for low bladder pressure?
2. What experience can you impart on testing/replacing motor bearings?
3. If I replace the motor, what are the important specs to match?

Anyone who says "call a plumber" for something like this doesn't belong in
this newsgroup and never did. They're out of their league. The people who
do belong in this newsgroup know something about home repair other than how
to use a telephone.

Moving forward for those who have experience troubleshooting motors, here's
the plate on the motor:

I'm not sure how a "jet pump" motor differs from a "pump" motor (do you
know the difference?) but I found this troubleshooting guide:

It's not hard to find a "jet pump motor" on the net, but it is almost
impossible to find *that* jet pump motor on the net. What matters?

The GE Model Lookup for repair manuals & parts diagrams comes up broken:

The well-tank not-empty switch is continuously closed (as it should be):

There must be a bladder-pressure switch somewhere but I don't know what to
look for yet - does anyone here have that knowledge of what to look for?

The gauge, if accurate, is indicating 70+ psi pressure at the pump itself:

The relay doesn't appear to show any visible anomalies that I can see:

I think (but am not sure) that thermal overload may be occurring:
