If you can do brakes, you can do exhaust mods and a pulley swap.

Fluids is a good idea. There is engine oil, transmission fluid, power steering, coolant, supercharger oil and brake fluid.

For plugs: AC Delco 41-101. For wires, a premium stock replacement, ideally with a lifetime warranty. You could get something fancy, but they're not going to help you with anything but lightening your wallet.
