Yes to all the above and never run engine that hot you will take out head or intake gaskets.

the water pump has nothing to do with the tempature. the pump just pushes the water threw the system. did you even check to see if the pump was working? 1st get a repair manual. check your radiator to see if the water is flowing ,also check the thermostat.
