Just make sure on the coolant to get all the air pockets out of the system. Check the belt really good on the groove for no small cracking.

If it were my car, I would go ahead and for sure change the brake fluid, but probably do all the other fluids also (tranny, differential, PS). Your plugs and wires are probably OK, but it's not that expensive to change them too (contact Gene at gmpartshouse.com for some AC Delco Iridium plugs and GMPP red wires). Might want to change the fuel filter too and you'd be set for a long time. And just make sure the belts and hoses are in good shape.
