Check the coolant level. If the check engine light is on, scan the computer for trouble codes. As far as the overheating, check to make sure the radiator doesn't need flushed.

Ok, how do I scan for trouble codes? And why does my heater blow out cold air instead of hot?

You need a scanner to check for codes. Most parts stores will do it for free. As far as the heat, see if both heater core hoses are hot. If they are, check the blend air door. If only one is hot, try flushing the heater core.
