Gearbox oil - Use GL4 oils, don't be tempted by GL5's or your synchro's will make you pay for it. If you can afford it, use a cheap GL-4 for a week or 2 to get things lube'd, then drain it & fill with Redline MTF (about $115 for 3.5L... Cheaper than a gearbox rebuild though).
Coolant flush, also check that the thermostat works, the fans come on & that the heater works (come to think of it, it probably won't - it also doubles as a filter for all the accumulated scale in the cooling system

)

If it's been sitting, I CANNOT STRESS TO YOU HOW IMPORTANT THIS IS!!! I learned that the hard way... Bend valves are not fun when the belts let go... Also, the tensioners are only about $35 each. They probably need doing too. Better to be safe than sorry.
Don't forget the brake fluid too - It'll bring you & your new car undone very quickly otherwise if the fluid has absorbed water.
Have fun
