Can anyone tell me the best plugs to get? Sorry if this sounds like a dumb question...just heard somewhere that you shouldn't use just any type of plug on the N*

If the car has the Northstar engine you want AC Delco #41-950, gap is preset at .050", torque to 13 ft/lb with a tad of anti-seize on the first three threads. Use the diagram to correctly connect the plug wires.

For your Northstar, use AC Delco 41-950 .050" pregapped spark plugs. That's the one and only spark plug which will last long / give you an easy life.

www.rockauto.com - the expensive set is the GM sourced correct length with the proper boots.

Make sure you hook up the wires correctly. use this diagram.
