First, I would recommend an 8" wheel, especially with the 32/11.50s. I have 33/10.50s. I used my stock 7" wheels at first but they were too squezed. I now have 8.5" wheels and the tread is more even across and should wear fine. With the skinnier rim you will have to run less air so you don't wear the centers out...I didn't like the way it handled like that.
I have a 3" body lift and the TT/Shackles and I get a little bit of rubbing up front. It only rubs when the wheels are turned. Some trimming may get rid of the problem. When the tires were on the 7" rims I had no rubbing at all.
I don't think the 32s will fit with just the TT...especially if you go off-road. Maybe someone has that set-up and can let you know for sure. If you do the 3" BL you will be ok...or if you have the money go with a 4" suspension lift!
If you don't want to spend a lot of money you can run 31s with the TT and it will still look good.
