that is one CLEEEAAAAAANNNNNNN DA. congrats on the purchase, you are going to love it! what's cool is that because your car is a 92+, it's obd1 instead of obd0, which means you have much more compatibility options as far as easy motor swaps. i would say the first place to start is making sure that it's up to date on maintenance. that will make a bigger performance improvement than "upgrades" anyway.
make sure
valves adjusted
fresh fluids (motor oil, tranny fluid, etc)
new gaskets (valve cover gasket, tube seals, cam plug seal, grommetts)
new air filter (k&n or a short-ram intake is a good idea)
new plugs, plug wires, cap/rotor

that's the stuff to spend money on first. once your car runs really happy, than you can start putting upgrades on it with your next round of spare cash.
