Why the lift? Looks? Bigger tires? How do you use the TJ? Offroad or strictly on road? A 2" lift can often be gotten away with with minimal other mods if your mostly after the stance and street driving. Doing it "right" is far more complicated. By right, I mean optimizing articulation and geometry. There is a lot to a good lift (more than I'll get into here). Two big things are:
1) shocks. You want your ride height to be roughly in the middle of usable shock travel. Useable travel is not necessarily the same as actual travel of the shock. It depends on tire and other clearance issues that are determined by cycling the suspension without your springs in. You may need different shocks.
2) driveline angles. The angles between the driveshafts and the transfer case as well as the driveshafts and axle pinions change with a lift and can lead to vibrations if net set up properly. This is a particular problem in the rear with a TJ because the driveshaft is so short. Transfer case drops, SYE kits and adjustable control arms are all used to address that.
To your questions:
Rear sway bar links-Don't worry about that.
Front sway bar disconnects-not necessary for lift but can be helpful in that they allow better articulation offroad (and therefore will make any clearance issues more apparent).
Track bars-both axles will move laterally with any lift (front to driver and rear to passenger). This won't be extreme with 2" of lift but adjustable track bars allow you to re-center the axles at ride height.
