Many things can cause the engine to not run smoothly. As far as the coolant, is it full? Is there any evidence of coolant mixing with the engine oil?
For the heater, I need you to check something. With the engine running, warm and the heater on high, see if both heater core hoses are hot. Let me know what you find.
