The trackbars will make the axles shift a little as you lift the Jeep. It's a good idea to look underneath and stare at things a bit so you understand what happens as your suspension goes through its range of motion. That knowledge will help you a lot as you do more and more to your Jeep (trust me, you will... I started with a 2" BB, too...)
As far as the axles shifting, you'll see that the track bars will swing the axles in arcs as the axle moves away from the frame. This is more pronounced the more the axle moves away, so it is more of an effect for taller lifts. In your case, the 2" BB doesn't move the track bar far enough away from the stock position to matter much. Each axle may move 1/4 " or so, no big deal.
For taller lifts, people usually install adjustable track bars or relocation brackets to account for this. Not usually worth it for a BB. I didn't worry about it then.
Your sway bars are fine, too, for a 2" BB.
The thing most people don't know or think about is to loosen all eight bolts that mount the control arms, so they can be torqued back down at the new static positions. Do this before you try to remove and reinstall springs, it makes it much easier.
