That's a nice looking Jeep. Depending on where you intend to take it, and how hard you intend to wheel it, you may find that it's pretty capable as it stands without modification.
If you are a new and relatively inexperienced driver, I would recommend that you do little if any modification on it to start with. A stock Cherokee is a pretty safe and stable platform, but once you start modifying it, its road manners may become less polite. I'd wait until you have more mileage on it, and until you've tested its limitations off road, before deciding how to modify it.
