When my 2005 LJ was still setup more for expedition than wheeling I had several versions of an ome setup. With a winch and winch bumper I ran a 934 front coil spring which was a little stiff off-road bit handled well on road. The best ride and handling in the front end was achieved with a 933 front coil and a 60047 nitro sport shock. I tried bilsteins and was never happy with the digressive valving.
Rear application will vary depending on your loaded weight. The 949 coil served me well loaded with a hard top or soft top and gobi rack. I didn't like the increased stiffness when this coil was paired with the 60049 sport shock. The next valving under this would be ideal IMO. With your half cab I would consider a 942 rear coil if your aren't going to load heavy.
With these two springs a 255/75 17 was a great fit with good road manners and available in a take off from newer jeeps.
I also highly recommend a quality set of control arms for a DD. Most will say it is unnecessary. It will be $1000. It was the best improvement I have ever made to ride and handling when set up properly. Look into preload on joints and squaring axles to frame. The above spring/shock coupled with a narrow tire and 8 control arms (metal cloak, currie, savvy). Will be a more than comfortable ride that is still fully capable.
