My experience with overheating has usually ended up being one of two things. 1. Fans not running due to faulty fan or the temp sensor on the radiator; or 2. If the fans run when activated by the appropriate temp then it is the radiator. I would go there before the water pump any day of the week. Over time the radiator gets clogged and it just can't flow water through the channels as well as it used to, which means less water to cooling air contact. It is first noticeable at idle, but in time it is noticeable as running hot in slow moving traffic. Then progressively worse until the day it overheats and you've got a blown head gasket.
