Finally got around to changing the water pump and timing belt, which still looked new after 15 years and 83k miles:
I would have been fine with running the belt even more, were it not for the pesky seepage from the water pump leading me to question the reliability of its bearing.
I am glad that it is all said and done.
Some pointers that may or may not be useful:
1. I used Otramms' excellent videos on YouTube to prepare for the project.
2. The first test to perform is loosening the rear bolt for the AC compressor. If you can do it, proceed; if not, take it to the shop.
3. There is a special place in hell reserved for the engineers that came up with the AC compressor mounting, I am sure.
4. Removing the oil filter makes access to the front lower AC compressor mounting bolt infinitely easier.
5. Removing the spark plugs makes rotating the engine much easier, and is a good excuse to put in new ones.
6. Check and doublecheck the new timing belt for correct placement before removing the pin on the new tensioner.
7. You will need swivel joints and ratchet extensions of different lengths, as well as a crankshaft holding tool.
8. If you go step by step, it is an immensely satisfying job to do yourself.
My thanks to ih8mud and all its members for the wealth of information and guidance that enabled me to tackle this job myself.
