Yup. That's the easy part. Changing the wires can be a pain in the butt sometimes, depending on how things are positioned (on a '97 Cavalier, they're not positioned well). And ignition coils, those are often not fun either, as they're not in accessible places.
It amazes me sometimes how inconvenient it is to change simple parts on cars. Thankfully spark plugs are usually easy to get to.
