Hey y'all!

I just got out of buying a -97 GC, so with the money saved I want to get some good things for my good ole XJ!
Having a discount of 5% at Rockauto.com I want to hear from you experts what might be a good idea to buy. I have a few items on my list already but since I'm ordering I want to get some extra good to have stuff.

1. Brand-name oil and air filter (maybe a couple)
2. New coolant reservoir, got a small hole in mine right now, maybe two of them. My XJ is a -90 with the closed system.
3. Cup holders! They're 6 bucks so wth...
4. New oil pressure sensor, if I can figure out which one... Cant figure out mine right now... I'm such a newb.

That's about it as of now.
I have some spark plugs, a no-name fuel filter, new distributor cap and cables which I will eventually put on, maybe when it gets warmer.
I'm looking for stuff to make the 4.0 more realiable, like upgrading important parts that are cheap but will make a difference. Like CPS, IAC and such..

Any other good ideas?
