It sounds like you need to get a handle on what the components actually do.

Driveshafts fail because of the tall lift causing steep angles on the joints. Disconnecting and flexing offroad can accelerate the wear, but they can still fail with nothing more than onroad driving. It has nothing to do with the fact that you chose OME vs Teraflex. Three or four inches of lift is still three or four inches of lift, regardless of the stamp on the side of the box. Same thing with control arms (caster correction). As you lift higher, the pinion tilts up and the caster goes down. It is automatic and unavoidable. At some point, the caster gets low enough that you want to correct it. For you, that could be two inches, or it could be six inches. We can't tell you how 'you' will feel about the handling. And same thing for the axles. As you lift higher, they shift further and further to one side. At what point 'you' want to correct that will be for you to decide.
