3/4 not necessarily out of normal range....

I'd say anything nearer than 1/8" or so from the red is probably really ok. If you're concerned, you're most likely looking at:
1. Thermostat (most likely)
2. Thermofan switch (quite common, and some will maintain a higher temp depending on their spec)
3. Blocked radiator
4. MAYBE water pump, but unlikely to affect temperature so directly
5. Something else I'm no doubt forgetting.
I would think your belt squeal is likely to be a slightly slack tensioner or old belt; maybe a dying tensioner pulley or idler pulley in the works there too -- check this, as they can seize their bearings and destroy themselves when you're least expecting it.
Crank pulley can make a screeching noise if its metal hub is separating from the rubber isolator. Do a search on harmonic balancer or crank pulley for more info on the diagnostic for that. Again, unlikely to be a heat generator or you'd be hearing that noise all the time.
Incidentally, your heater core is always at full flow, so turning the heat on only cooks the car's occupants. No benefit to that -- turning heat up only opens an air flap to allow the hot air into the car.
