Glenn,
The Water pump typically goes bad when the seals fail and it starts to
leak. If it isn't leaking, I doubt that is your problem. As to the
temperature of the engine, Mid range on the gauge is correct (maybe even
a little higher). If you have done all the things you mention and it is
still over heating, you may have blockage in the coolant channels of the
block.
