I believe if you look in your manual it will tell ya which you need I believe. The Big ones are 15K, 30K, 60K, 90K, and 120K i think all the rest inbetween those are little things like oil changes and just an inspection of things.
Besides oil, I'd change the antifreeze, flush the transmission, and change the fuel filter if you haven't done that yet. If you have a 4x4 change the transfer case lube (it's ATF) at 60k.
