If it's stock, it has points. The first thing I'd do is get rid of the points and install a Pertronix kit. They're bullet proof and easy to install. The link below may or may not be the exact one, but gets you close:

They're available from many sources including Summit and Jegs. After that, as you've suggested, new plugs, wires, rotor and cap and you'll be set for many trouble free miles.
