Has it been started at all during that time, or the engine cranked over?
At the very least you should change all fluids, give it a good tuneup and mechanical inspection (such as brakes!).
You'll want to drain the old gas out of the tank and fuel line, and may need to give your carb a good cleaning or possibly a rebuild to clear out any varnish from dried gas.
Change the oil, adjust your valves, new plugs, distributor cap, rotor, etc. Timing.
Do you remember what all was wrong with it when you parked it? You can overlook a lot of things when you're a teenager and forget about them during the intervening years.
Pull the brakes apart and check the condition of the components at each wheel. Adjust them. Replace the brake fluid and bleed the system properly.
If you take the time to do all that now, you'll avoid potential unpleasant experiences that might make you wonder why you bothered keeping the car all this time.
Hope to see you back here telling us about the big smile on your face once you get the car back on the road!
