My head gasket is leaking, my car seems to be running a little hot, does this mean that my gasket is about to blow?; also I'm no longer getting heat

:(

Pretty good chance. Get it fixed, before you warp the head and damage the valves.

If the head gasket leaks period, it is considered to be blown. You have no heat because you have no coolant. Keep driving it and you will have a pretty planter for your flowers on your front lawn.

Yep, time for surgery...
