Since so many people are talking about me I thought I'd chime in.
First things first, as mentioned youll need atleast a 15x8 wheel for your 33s if your going to go with a 12.5" wide tire, and you' ll need atleast 3.75" of backspacing which can be achieved with proper aftermarket rims or spacers. Also you'll need wider fendor flares, if your concerned about tickets, as your tires will now stick out.
I paid $1200 for five wheels ( stock Jeep Ravines used), tires (3 used, 2 new), 4 spacers, and used fender flares.
Next thing I did was the motor mount and body lift. In my case this was to avoid doing a t case drop and with an sye cv shaft combo in the future allow for a tummy tuck skid plate.
I paid ~$ 200 with my lift kit.
I drove and wheeled a couple of times like this with the only issue being some power loss at high speeds due to the 307 gears.
At this point I spent a year thinking about what I wanted my jeep to be able to do which I suggest you do to. In my case it is currently a daily driver, which I wheel occasionally but in the future when I can add another vehicle to the fleet the TJ will be for hot summer day driving and wheeling only. In which case the parts I chose would be suitable and or upgradeable.
Unfortunately I cant tell you much more about prices as I bought used, traded up and did a lot of the work myself with friends. And the parts I bought new are the same price wherever you go. My suggestion take your time, check kijiji and the for sale forum in here often, make some friends and enjoy it. You will spend more then you planned and at that point you wont care cuz you will have now caught the disease!
