Default 90K Service - plugs, timing belt, water pump, what else?

Getting prepared for my 90K service (even thought its still 20K away), but I'd like to make a list of parts to get. So far the only things I can think of are

1) Timing belt
2) Water pump
3) Spark plugs
4) Lower ball joints if necessary.

What other things should I get? Any accessories such as gaskets, pulleys etc while replacing these parts? I know on my Honda i replaced timing belt pulley, valve cover gasket, and I think some sort of a tensioner.

Coming from someone that has done this procedure twice, I would say that you need in addition to what you wrote...
1. Timing belt tensioner
2. Fixed timing belt bearing
3. Swivel timing belt bearing (this one tightens the belt when the tensioner pushes it.)
4. Red Toyota Antifreeze..(have to drain it)
5. Thermostat (You are IN there, so change it).
6. Thermostat O Rings 1 for thermostat, 1 for gooseneck
7. Water pump O'ring (Should come with water pump, but check to be sure)
8. Camshaft seals 1 for each side
9. Crankshaft front seal
10 Loc-tite for large crankshaft bolt (good luck getting this one out)

Other things

11. Good time to check hoses (upper & lower)
12. Power steering flush

I did this all to my second 99 GS in 2005. My first one was wrecked in 2004 JUST after I finished the timing belt.

GOOD LUCK!

Anyone got a picture of how to access the timing belt, tensioner, and pully?

If your mechanically inclined, it's easy to do it yourself.

A new timing belt is not needed? Only tensioner and bearing adjustments? When is the timing belt service?
