If you do not have a set of plenum gaskets on hand, get some.
Keep track of your screws! In the pump alone there are 16 screws - 4 different lengths and two head styles.
Even though the FSM does not mention removing the plenum, do it anyway! You will need to remove all three AC compressor screws and wedge it up a bit or you will NEVER get all 16 screws in the pump to line up and you will cross thread a couple. Clean your screw thread really well, it will help.
The pump to thermostat hose is a real challenge to get off, especially if the factory spring clamps are still in place. I went ahead and removed the alternator, the oil pressure sensor and oil cooler lines to make more space to work. I also loosened the clamp on the receiver/dryer so it can slide up and down. This is a good time to replace the hoses if you have any doubts at all about their integrity. I considered removing the oil filter adapter also to make even more space to work but figured that might be going a little too far.
And that is where I am...
My hoses came in yesterday. I will resume work when it warms up next week and will report back if I have any further issues.

I finally finished up the water pump job along with new silicon hoses. I cleaned up a few things under and around the plenum before bolting it back down. The air horn cleared the alternator and went back on fine, so I guess I got lucky on that one.
The hold down clips for the IAC and IAT broke, I need to scrounge some of those up.
Over the course of the next two days I pushed 3 gallons of 50/50 classic green into the system. No leaks!
I'm on the road again, now for a good wash.
