Unless some other event stripped the teeth (broken valve stem, trhown rod) you should only need the items normally associated with changing a timing belt WHICH, if you're smart, will include EVERYTHING that turns by or against the belt (besides the crank and cam pullys). water pumps, idlerbearings, tensioner bearings etc. Not sure if this engine is prone to leaking seals but you might consider that as well.
