Oem spark plugs!

So confused. I need plugs and wires for my 02....I think. I only have about 36,500 miles on her but the plugs and wire are original. It has to go into my trusted mechanic for an alternator change so I figure why not do a plug and wire change at the same time.
So....do I need to replace them? If so, which part number for the plugs? 41-110? EBay has them for $22 for a set of 8. If you get a $3 rebate for each plug, I'll end up $2 ahead. Something doesn't add up

All 8 plugs (real AC, but came from china) had to be re-gapped from .025 to .040. Don’t know what happened over there,
the packaging looked pristine....
I like that it fits a little loose with an air space inside.
You see a similar material over the brake lines on the C5.
I will be the guinea pig here. I don’t have headers, but using my new wires naked. Will post how they hold up.
