Don't want to break your heart here, but it wasn't so long that I was a wide-eyed teenager with big dreams and an empty wallet. At least one of those two things has changed in the intervening years.
Your first concern, unless this Jeep is a toy only, is a vehicle that is 100% reliable. You can budget for upgrades, but budgeting for break-downs is harder, so work to avoid the break-downs. Oh, and chicks don't dig cars that break down when you take 'em out for the evening, totally spoils the mood.
With that in mind, I'd look to what your needs are, and start there. Then find QUALITY stuff to put on to meet those needs, and do it in logical steps. Get an SYE in sooner rather than later, as it will save you from having to rig stuff up later. Then figure out what your plans and budget are for tires and suspension, and go from there. Do it right the first time with quality parts, properly installed.
Big lift and big tires, done properly, costs big money. And it makes the vehicle less useful for everyday tasks. Keep this in mind.
Hate to be Mr. Practical here, but I've done both - my high-school habit was British sports cars, college habit was the Brits plus street racing a 67 SS Camaro - and going with practical for the past 12 years has ultimately been a lot more fun in the long run.
