The offset will allow for wider tires and more clearance, but you would still need an adjustable trackbar to center the axle, dependent upon lift height, over 2''.
If you stay with a 1.5'' lift, an aftermarket trackbar is not required. The axle shift is minimal, in my opinion.
You would not...
That screen door closer can be the difference between death wobble and not.. I prefer never having to experience that s***. I've broken mine twice offroading and had to limp home under 40mph.
YES, I would highly suggest an aftermarket stab. The trackbar is optional, but the stab will better control the larger tires. However, your axle will be off-center after the lift, so an adjustable track bar is highly recommended.
