If you have no documentation about the service done by the previous owner of your truck, you could do the 90/100k stuff early if it will make you feel better and if you have the spare time and money now. There's lots of info online about the recommended maintenance intervals. Check this site:
I recall several threads saying there is no fuel filter in the 2nd gen Tacomas, just a screen around the pickup in the tank. Air filter
replacement is every 30k unless you have an aftermarket filter. Also you might want to inspect the serpentine belt and brake pads/shoes. Transmission, coolant and spark plug service is at 100k. That's all I can remember without looking up this stuff. Hope this helps.
