OOOhhh... you are in so much trouble! You have been bitten... "Should I go bigger?" If you are asking that before even getting your tires, you are in trouble!
I wouldn't worry about your CV boots yet. There is accelerated wear from the increase in angle but it's not all that severe. You have time. As for adjusting the torsion bars, an electric impact wrench is not necessary. Spazz and I have found some of them don't work past a horizontal plane anyway. I got a 3/4" slide bar and socket at Sears that works great to adjust the torsion bars and remove big stubborn nuts on the vehicle. You can put lots of leverage on that thing and it makes it easy to make several full turns on the adjuster nuts without ever removing it. Many auto stores have sales on combo packs of floor jacks and stands right now - tis the season. I would stay away from Wal-Mart though - is no bueno.

Those are some good looking wheels! Post pics when you get everything mounted up. I plan on stepping up to 33" BFG A/T's in a few months - they have a great rep as a nice, jack of all trades, light truck tire. You could call around for shops that carry blems (factory asthetically blemished tires that fetch a discount price).
