You won't need the adjustable panhard bar for a 2" lift.

I run rear airbags in mine but only because I tow a camper everywhere and carry a fair bit of weight in the back. So unless you are really loaded up, the airbags won't be worth it for you.

If you are happy with how the OEM steering feels then stick with what you have. An adjustable damper is good for firming up the steering if you a running larger tyres or just want it to feel tighter but you don't need it for a 2" lift.
