well, if you plan on starting it AND driving it I'd replace ALL the fluids including drasining and replacing the gas, coolant, brake fluid, and engine oil.
Replace the fuel filter and oil filter.
BTW, since that coolant has been in the motor for AT LEAST 10 years (who knows how many years it was there before parking the car) you may want to open up the freeze plugs on the block too to get all the coolant out. Without doing that and simply draining the coolant from the radiator you leave a good 1.5-2 gallons of old coolant still in the block to contaminate the new coolant.
I'd also very carefully check all the rubber hoses, particularly the fuel lines since they may have dry rotted. There are rubber fuel lines at the tank itself and also up front that go from the hard lines to the fuel pump.
might also be a good idea to pull the electrical plug off the distributor just before trying to crank it over. This will allow you to crank it over a few times without it starting to get oil thru the system. Than reconnect the plug to the distributor and fire her up.
