here's my situation, i have a new 2012 wrangler unlimited with the basics. i am planning on putting 16in pro comp wheels along with 33's tires. would also like to lift it about 2 inches just for looks. looking at the 2.5in teraflex bb. would i need a aev procal module, re- gearing, or any other modifications? also will i need a spare tire spacer for the spare tire carrier? any info would be helpful.

I'm no expert but the the AEV procal will cover the larger tires and lift. The gearing depends on what you have, currently, and what you plan on doing with your jeep.
I have a 2012 JKU sport with 33" tires, 3:73 gears, and no lift and used the procal to recal my speedo/shift points.
Also, the wheels will need a backspacing of 4.5" or less or you will need wheel spacers, and my 33" with 17x9 wheel spare fit factory tire carrier fine.
Good luck!

2" lift with 33 x 12.5, I didn't have to use a procal, . No need to Re-cal for speedo, my gps shows same speed as my gauge. Might consider re-gearing as I lost power on my 6th gear. And no need for spacer for spare, my buddy runs a 35 on his spare tire carrier.

with 2 "and 33" believe that it is not necessary the procal module, anyway don't you think best idea a kit 2.5 "with springs instead of BB, I took him in my jk and works very well

Below is a handy calculator which compares gearing and tire sizes. By playing with it I have learned that 35's with a Jeep that has 4:10s performs like a stock tire on 3:73s.
Moving to 33's will impact your torgue which is not what you want to lose when offroadiing.
