Nice looking Jeep. Looks clean! I see you're in LA, so you probably don't need to worry about Rust. First thing you should do is boring stuff. Maintenance, top to bottom. Fluids, Spark Plugs, Air cleaner, Brakes, Brake fluid, Coolant, Transmission fluid, etc. Its got a 100k miles of who knows what kind of maintenance. So, anything that is a "wear" component should be inspected and replaced if its not up to snuff.
Next, Drive it. What do you want to do with it? Beach cruiser? Rock Crawler, Mall Crawler? No wrong answers...but decide what YOU want to do with it, don't let others talk you into spending 10k plus to run 35" tires if you don't intend on taking it to play in the rocks. If you just want a daily driver...a rubicon on 31's is a sexy machine. The proportions are just about perfect. If you want bigger tires for looks...you don't need to spend a whole bunch of money on the latest and greatest from Savvy, Currie, Metalcloak, Clayton, RockKrawler, etc. Something like a BDS, Zone, or Pro-Comp lift will be sufficient. Pay attention to shock choices. They, along with making sure you don't have hard parts hitting other hard parts, will go the furthest toward creating a good ride.
