For starters you need to ditch the 4" lift springs in the rear, you re never going to lift the front 4" to level out the rig, other than using a 4" bracket lift kit.
4Crawler has a much better price and he has been supplying them the longest. You will also need new upper and lower ball-joints, an alignment, and longer shocks. You can get longer shocks from NAPA for about $20/ea.
To clear the 32's, this is what can be done(cheapest option first):
1) BFH to clear them in the front, not suspension lift needed.
2) 2" body lift, no suspension lift needed.
3) 1.5" BJ spacers, and 3" longer shackles
For all of the above, I would add an additional main leaf spring to an oem packs. The additional main leaf will support the weight of the Runner top, wont stiffen the ride, and will prevent the sag you see on most Runners and trucks w/camper shells.
Unless you are running a winch bumper and winch, don't expect the 26mm bars to ride that much better than the stock bars when cranked up for the 1.5" of lift.
