Fundamentally, you are correct --- there isn't much that can be done if you don't have adjustable control arms. Toe-in and drag link are all that is adjustable, and the trac bar if you have the adj version.
I agree that it can't hurt to get it aligned, but I did not. I adjusted the drag link to center the wheel and that's it. Toe in should not change as a result of the lift.
I do have the Moog Steering Stabilizer. I did feel the IRO bushings in the trac bar were a bit loose, so I did install the KOR hard bushings as someone noted. I think it's an improvement in the feel of the front end.
I may also try the relocation of the SS to the "drag link / trac bar" location rather than the stock "axle / tie rod" location. I've read that it can improve the "solid feeling" of the steering in the WJ.
All-in-all I have never had DW, but the steering does feel a bit loose, almost an "over sensitive" feeling, or "over-assisted" power steering.
It's not horrible, but enough so to see if it can be made better.
