It's an SE, base model, D30 high pinion front [maybe] D35 rear, 4:10 gears. The D44 was an option but most who bought an SE did not spend the extra $380 for the upgrade, you'll have to eyeball it for sure.
First off, the D35, there is a 'super35' kit available with heavier axles, carrier, etc. Don't go above 4:88's on the rear, you can fit 5:xx in there but the gear tooth contact area will make the ring and pinion gears tend to break under stress.
The D30, good axle, but again, stay with 4:88 as the max, tooth contact really comes into play above that, 4:56's will drive 33's nicely and 5th will actually be usable.
Tires, I'd stay with 33's max, above that keep a spare axle or two in the back and learn how to replace them in the woods. If it's for street, 35's and 4:56's will work but 5th will only work on downhills with a tailwind
Suggestion, 4" lift, 1" body lift, 33's, limited slip auburn in the back and ox locker, aussie or E locker in the front. It will flex like crazy, be very driveable, the limited slip in the rear won't over stress the rear D35 and the D30 front will have a selectable locker as you need it. You will also need a motor lift, transfer case shift linkage kit, adjustable track bars, thats pretty much how we have done the last 5 or so this year.
Another option depending how handy you are, D44's can be hard to find, Chrysler 8.25's out of a cherokee much easier, the main difference between the 44 and 8.25 is 1/4" smaller ring gear size difference, D44 is 1/4" bigger, the handy part is you need to cut the leaf spring perches off and weld on coil spring sockets. Around here you can get 8.25 rears out of XJ for $100 complete, don't know about your area.
