Jeeps are definitely easy to learn on, I'd been trying to learn on an Evo and a Saturn Coupe when I found my first Jeep (94 YJ) and I was so worried I wouldn't be able to get off the lot since I could barely drive stick and I was amazed at how much easier the Jeep was. The clutch on my TJ catches much better than the YJ ever did (lots of factors), but I think mostly it's because you really have to rev the Jeep to get the weight of it moving so once you're moving it's just knowing when to shift, how long to leave the clutch in.
If I can offer any advice on the first purchase...don't worry about color, I know that sounds stupid but I passed over a great deal on a jeep with diarrhea color interior with such low miles and I always regret it,lol. I'd always suggest something under 100k unless it's had recent general service, brakes, diff fluid change, rms, battery, radiator, etc. All those things seemed to hit my TJ right at 100k. Be less concerned with tires/wheels you can find them easily enough on craigslist, same for "new soft tops" and seat covers, don't let them make up your mind, focus on the mechanicals.
