deffo the cambelt/tensioner on the engine along with a service, even if your not planning on keeping it tooo long, its just peice of mind, cause if they fail theyll cost you lots!!! (unless previous owner had proof of it being done recently)
if the rear brakes decide to play up/seize up, upgrade the pants mk2 rear calipers for mk3/4 version, there a direct fit and will save you loads time/effort when it comes to mot time
body work wise, well never done it me self but what oakie^^^ says above sounds good if your keeping it long term... never had mine long enough to do that kinda stuff!!
