Water pump replacement

I have a 1993 Pontiac Sunbird with a failing water pump, I have some friends that seem to believe that I will need to take the timing belt off the car to replace the water pump. Do I need to take of the timing belt to replace the water pump ?
Also, is there anything like engine mounts or any other major task that has to be done before removing the water pump ?
I have never done a water pump on a Sunbird but I did a few on Neon's and Intrepids are they similar to replace as a Sunbird?

Isn't that a 3.1 in the picture Ras? He has a 2.0 belt driven pump. There are 3 duplicates of this question.
