service? um... well i would replace the timing belt to start with. its kinda tricky to do but after 7-8 times it only takes you bout 2 hours

and if i were you i would replace it with a kevlar belt not oem, i had an oem belt snap in half on me, and another shred the teeth off, cost me 2 whole valvetrains. the kevlar is bout triple the price of oem but its well worth it. considering it cost $300 for a whole new set of valves, not to mention the fun time you will have lapping them all in /ubbthreads/images/graemlins/laugh.gif other than that, change your oil and filter, probly change your tranny, transfer, and diff fluid just for kicks. and you should be okay for a while /ubbthreads/images/graemlins/smile.gif oh and don't forget the fuel filter.
