1994 Toyota Camry Question about Engine

My car was making a noise like gravel in the engine. I learned that this was a water pump issue. My car die on the road. There is no water in the radiator because of the water pump dying.

Should I have the mechanic check for leaks in the radiator, the head gasket, campshaft oil seals and timing belt?

What other damage could I have done driving it with the water pump out. The car was hot before it died.
