The taller the tire, the less power you will have, so your Jeep will be slower in the higher gears.. Hence, no one will argue against re-gearing, but it is expensive and many just live with the power loss. I have a 3.73 rear end and I don’t see that much of a difference except my overdrive is almost useless on the highway. Around town, it’s not that noticeable.
Asking “what you will need to run 33s” will get you answers all over the place. As you can see, you can spend far more than the cost of the Jeep itself… You can spend $6K or more on just one axle, to “run” 33s.
If you’re driving mostly street, and you’re on a budget, you don't need to spend huge money on suspension and axles. 3" of lift will be fine for 33s, you can get that cheaply with a 2” budget boost and 1” suspension lift for a couple hundred dollars, and a set of tires and wheels for $1,500 or so. So for around $2K, you’ll be good to go. You could go for 32s and just the 2” budget boost as well. This looks very good, not that much different than 33s.
This was my LJ with 2” lift and 32s:

Hey guys, I'm in the middle of doing the Zone 4.25 lift, actually going to try and finish it up tonight. I was able to get the entire kit (3" SL, 1.25" BL, MML, Sway Quick Discos) and 4 33x10.5x15 BFG Ats for less than $1200...

I'm doing most of the work myself besides the tire installation, so you really don't have to spend $3000+ for this setup.

Also, I'm seeing people tell him he needs new rims for the 33s if he has stock rims...I have the stock rims also but have been told that the 33x10.50x15 fits the stock rims..is this not the case?

With 10.50s, stock wheels should be fine. Most go to 12.50s with 33s. The extra width requires a different offset, moving the tire/wheel outward.
