I am thinking about the same route, more or less... I already have a 2" BL kit from RRO, and am waiting on +1.5" springs. Will install everything together. For this type of lift, you don't have to worry about driveshafts or lowering front diferentials, etc.
Iwas thinking of 29" tires (which later will probably turn out to be 30", as they will be reconstructed), and expect no cutting.
I am not aware of any LSD for the front end.
