I'm running no sway bars, around 6" of lift and 35" tires, has body roll but is stable... No steering stabilizers and drives just fine even with the alignment all over the place (it pulls to one side some, and camber isn't perfect, caster isn't great either with just the radius arm drop bracket...), with TTB unless you're doing something top heavy or trying to go fast on the pavement, I don't think sway bars are needed.
Like adsm, I ditched the sway bar with the D35 swap, have thought about installing one but I just got used to the body roll. Even though it's mostly driven offroad, it has towed a fair amount with no ill effects.
For your steering, you kinda need a drop pitman arm, they're spendy but not too bad for the small drop arms...
