Hello,
It could be a stuck closed thermostat for the overheating.
First of all you need to find out where it was leaking from.
When an engine overheats it can leak coolant from various places.
It could have a ruptures hose, or it could be leaking from the radiator cap due to excessive pressure.
The over heating can be caused by water pump or a clogged radiator as well.
As you mentioned your heater quit working, which means that the coolant is not flowing thru the heater core. It could be for a stuck thermostat or could be a clog in the system.
When you have a stuck closed thermostat, there will be noticeable temperature difference between the upper and lower radiator hose, due to no coolant flowing through the engine.

The engine can also overheat due to inoperative cooling fan. Verify that your fan does come on at operating temperature.
I have attached diagrams for your reference.
Please let me know of any questions.
Thank you
