Unless there is obvious, easily seen damage to a piston(s), all you need are a gasket set and the rings. Lap in the valves by hand and you will have done a '50's style overhaul (valve and ring job) and be good to go for many more years.

X2. Just decide to do the complete job while you got it opened. Sure it is easier with the engine out of the car but if you can get someone to lay on the floor and handle the lower end wrenching while yo slide the pistons in it is a fairly easy project. Go with new rings or you will be there again sooner than you want to be. Caution: When I replaced pistons (if you go that far) I ended up with a domed piston instead of the flat ones and had to "foil", measure and do a bit of Dremel head machining to get the proper clearance. Check clearances before buttoning down the head...Don't ask!
