Welcome and congrats on the new ride...
First you can look at the Toyota's official recommendations here: Toyota Parts and Service
I am going to make two assumptions: 1st you don't know the maint status, 2nd you want to drive this for many years to come.
1) Figure out the status of the timing belt and change that if necessary.
2) Fluid changes front to back (Differentials, Transfer case, transmission, radiator and I might go so far as to flush the brakes too.
3) Spark plugs
4) MAF cleaning
5) Cabin and air filter. (I am not 100% sure if that year has a cabin filter).
6) Think about adding an aux transmission cooler. Some 3rd gens as they age may create the dreaded 'pink milkshake'. Search that term for more info.
If you have some good service records then play around on the above site and figure out where all of the big items lining up for you. Good luck!

In addition to what Chris posted, you should lube the drive shafts. These trucks are supposed to have the drive shaft lubed during every oil change so you should get a grease gun if you don't already have one. Using the 4WD is actually part of maintenance too. Find a dirt road and engage 4WD then work through the ranges. I would try to find the service history of the transmission if possible since a fluid change for that may be due. Good Luck!

strongly consider synthetics
Flush every fluid possible. If timing belt/waterpump has not yet been done it is overdue. Power steering flush will prolong the pump's life. Note: the power steering pump uses Auto Tranny fluid, do your homework before starting.
Strongly consider synthetic diff. oil for both front and rear, and may as well go synthetic oil while at you're at it. I believe Auto Tranny Fluid may also come in a synthetic version. Change that auto tranny fluid frequently, perhaps even more often than recommended. Tranny and power steering ....
Again the presumption is you want to keep this rig running flawlessly. A bit more money on these crucial fluids is cheap compared to replacing parts.
Have the alignment checked... get some opinions on the steering rack, tie rods, idler arms, all of the front end suspension components. Ball joints have been known to fail-usually at around 200K miles, but it can be disastrous so have them checked somewhat regularly. When in doubt change it out, cheaper to replace unbroken parts than risk a road incident, tow bills and so on....
Congrats on your new to you ride. Sport editions highly coveted in these parts:hatsoff:
