The spark plugs along with the plug wires are hidden very well... The spark plugs are located under the log plastic strip on top of the valve cover.
Disconnect the battery, remove the spark plugs wires and boots and remove the spark plugs. Put in the spark plugs, replace the spark plug wires and boots, and connect the battery.
You will see wires right on top of the motor. You can easily follow these wires to the spark plugs.

On the top/ middle of the engine under the ignition wires. Two ten mm nuts hold the wires on Remove the nuts and pop of the wires....the plugs are in those 4 holes

No you do not need to replace any plugs at all when replacing wires.
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
I used aftermarket wires and did have some trouble with them. I ended up going back to Saturn for new wires. Plugs you can get anywhere. Don't try and upgrade them though, have them give you exactly what came in your vehicle from factory.

Refer to a service manual for complete pictures and torque specs. Overtighting the plugs can lead to a damaged engine
