valve cover is easy i'm surprised it wasn't done when the plugs were done.

at your mileage, I would replace diffs and transfer case fluids, brake fluid flush if it hasnt been done, tranny fluid (you can read threads on whether you want to do this or just leave it "lifetime"), check your belts for wear and tensioners for noises, and I would check your expansion tank for cracks or leaks, and cooling hoses as well.

Pixels on stereo you can have fixed for about 150 or so, I'm about to get mine done on my speedo cluster, the battery/alternator thing you need to check voltage and maybe have your battery tested? if its original battery, I would replace just for peace of mind, you are looking at 12 years old battery lol.

does the passenger side open from the inside when you pull the handle on the inside and push out? if so, your door carrier is busted.

good luck, she looks great and good to see another jerseyan! where in NJ?
