Hadn't started mine in 6 years. So I took out each spark plug and gave a quick spray of penetrating oil in each cylinder. Then I poured half a shot glass of marvel mystery oil into each cylinder before cranking it over. Cranked it over a little and let it sit for another day or two in the fresh oil. Any oil should be better then nothing- doesn't have to be marvel mystery oil. Now I'm driving my car daily after one year of restoration and the engine seems solid.
Other things I did:
replaced filters
replaced all fuel lines (used Racer Chris's stainless line through the tunnel)
bought rebuilt brake calipers for the front
replaced rotors with new
rebuilt front suspension (the rubber A arm bushings go bad and need to be replaced)
replaced ball joints in the front
new wheel bearings in front
new tires (well... good used ones)
new boge shocks in front
replaced rear calipers with 'good running' calipers off parts car
bled brake lines by using a long 'return' tube (3/8"?) to hook the caliper back up to the resvoir tank while I pumped and monitored bubbles going through the long tube
other things that I did that you may be able to put off until later depending on your cars condition are:
treat rust

oh and,
