15 minutes with the search feature will answer every question you asked...but anyway.

You can crank the Tbars, but leave room for you index finger between the UCA and upper bump-stop - it probably won't cause any problems. If the steering does wear out in a year or two, you can spend $350 on the calmini steering system and you surely won't have problems after that.

I wouldn't do both the body and suspension lift unless you really want to get high. The cheapest option is to get shackles ($50) and crank the front. It also gives you better droop (good for offroad). AALs will beef up your rear springs and provide lift but won't do anything to improve suspension flex. The body lift does nothing but adds room for tires, but it has the advantage of not stressing your steering system as much as a t-bar crank.

I have shackles, TT, and 32s on mine and it works well.

Also, get a set of bilstein shocks - they are a huge upgrade and everybody should do it, whether lifting or not.

Search and you'll find much more detail.
