so if i crank my torsion bars to get 2 in. what would I need to do to level out the back. Also, what size tire could I fit?
The torsion crank DOES level the front with the back. Torsion crank to level and you can fit 265/75-16 or 32x11.50-15. Know that whatever amount you "lift" it by doing that is also how much downtravel you lose, because all you are doing is adjusting the suspension downward.
Is your Edge 2wd or 4wd?
If it's 4wd then the Superlift kit for $1300 is about the only game in town.
If it's 2wd then you can use dropped front spindles and use an add-a-leaf or shackles or taller blocks in the rear.
On either 2wd or 4wd you can use a bodylift which doesn't cost a lot but the install will....which would still be cheaper than the Superlift.
The mac daddy setup are the kits from RCD or Dixon Bros. which cost a boxcar load of money.
Should I stick with 15 in wheels or can I move up to 16's?
15" tires are cheaper than 16". If your stock wheels are 15", they are 7" wide which is really too narrow for a 32x11.50. 15x8 rim with 3.75" backspace and 32's will slide right on. You could also use a 265/75-15 or 31x10.50-15 on the stock 15" rims, which would not require you to lift the rear at all, just a TT up front.
