Also replace ALL the screws holding the water pump on with new ones of the same size/thread. After all of the heating and cooling the bolts can become very brittle. When I did my WP the first time (long story...) I ended up snapping off 3 of the bolts off in the old housing. Its a good thing I had a spare or else it would have been up to the screw extractor. The 10mm screws holding the fan on are definitely a PITA--a good soak in PB blaster and a good set of tight vice grips make them pretty easy though. Good luck, let us know how it goes. Be sure to order the gasket as well.

As far as the alternator bolts, I'd tighten them down pretty good so the entire load isn't resting on that little tensioner bolt. If that bends you'll have to order a new one since they are an atypical sort of thing. Tension the belts just as you would normally--enough not to slip.
