100k service, I would do the following.

Aux belt, aircon belt.
Oil Filter

Fuel Filter
Radiator Flush
Spark Plugs
Gearbox oil
Diff oil
Transfer case oil
Brake pads, if need replacing
Safety check.
Only the timing belt and plugs? Thats a bit too much
For my 32GTR, I bought the service kit from Kudo's Motorsport. Got the timing belt, water pump, idler, tensioner bearing changed, raidator flushed for around $950. The labor was $500 flat. You can change the spark plugs yourself, it ain't that hard dude.
