Toady.....
If the water pump has run for 92k miles, there's a good chance that the impeller blades are worn or even broken. In he real world this can point to poor pumping action so less coolant is pumped around the system......maybe it's just general wear and tear causing the slight overheating, so replacing the pump & t'stat as you mention may be the way to go.
