How do I replace the thermostat in this car? Also I was told there is more then one how do I know what one I need if this is even true was not aware there were more then one in cars seems wrong to me, or is there another way around this see what is happened. My thermostat seems to be stuck open causing my car to overheat, but only while I am staying still when I start driving it cools down. Can someone help? Please!

Sounds like it may be only partially stuck open, it would not over heat if the thermostat was stuck open, it just would not reach operating temperature. Have you also checked the actual coolant level? Start with basic things, make sure the fans are coming on also while the car is at operating temp and at idle. Turn the air conditioner on, both fans should come on also.
