Old McDonald "88 YJ"

Finally, It only took 66 years to get my first Jeep !!! I have wanted a Jeep for as long as I can remember, probably while I was still in the womb !!
I purchased a 1988 Jeep Wrangler YJ - 4 cylinder/2.5 L - 5 Speed Manual Transmission - Red Color (of course) from a friend that got it from a friend that had in stored for quite a while.
Before I purchased it, he put a new Battery, Master Brake Cylinder, Fuel Pump, tuned it up, basically made it Road Ready !!
Warning !!!! I will be asking a lot of Newby Questions that will probably be having you slapping your forehead and saying a few cuss words and calling me a stooooopid *^&%#*&^%$#@, but that's OK with me.
I have OCD, ADHD, AC/DC or whatever you call it, so I want to know as much info about this Jeep as is humanely possible.
The Exterior is in Good Shape for the most part, I need 2 side mirrors and if possible just replace the clear plastic window above tailgate.
The interior is in need of some Tender Loving Care. I already took off the tan door panels and removed the worn out rear seat. I will be removing/painting/covering up all the tan parts in the interior - just not a color that fits with a Red and Black Jeep.
Thanx in Advance and I Appreciate Yawls Patience - Yea, I be a Native Texan.
