Sounds like your cooling system is working just fine. The low speed fan comes on at 218F and the high speed comes on at 228F. In traffic, you have no airflow until the fan turns on. Go with the "Anycolor" version of coolant and you are in the no worry zone.
On the window, sounds like your regulator needs to be lubed up. Pull the door panel and check to see if it's full of dry thick grease. Clean and apply some white lithium to it.
