You'll find guys that wheel on 40 inch tires, and a D30 up front, and swear by it. You'll also find guys that have destroyed complete one tons on the trail. Everyone has a different opinion because everyone has a different style of wheeling. You'll learn more by going out with your local jeep club than you will spending equal time hunched over a computer. You'll learn how you like to drive, how you like to approach things, what makes you uncomfortable, and what you're willing to sacrifice. You can read tons of threads on a lift kit, but ride quality is subjective, and lift height is generally different because everyone's jeep doesn't have the same weight added. (Read as bumpers, winches, lights, etc).
Just be forewarned that the more risky you get, the bigger your bank account could get hit. My jeep is the daily driver, so I keep the in mind when I wheel. Some of these guys park their jeep and drive something else to work. Please remember that when you ask for advice/try something someone else has done.
