Well, there are a few choices. Since you can weld that hopens up the gates. Still how much do you want to spend and where do you want to take the jeep? Dirt roads? Rock piles? Mud, sand, etc...
There are many basic suspention lift kits for the YJ. Most are old technology and can be rather stuff. If I was going to go with a conventional off teh shelf kit, I'd go with a Rubicon Express 4.5" XD lift kit. It's one of the best out there. (OME is good but won't clear 33's without help.) There are coil kits like the Pro-Comp 5" lift but it has lackluster performance compared to more inexpensive options. Black Diamond makes a 6" Coil-over kit which is nice but $$$. Lots of cutting to get it on there. One of teh more popular options out there fro YJ's is to do a SOA. This is relitively inexpensive if you can do the cutting and welding.
If you do your homework, it will probably be one of the better options. Then you have some guy's doing SOA up front and SUA in the back. This gives you a but more stability then the regular SOA and works well for a daily driver.
Although if you've got $$$ and like flash you could go with a Fabtech kit. Also, if you know a think or two about geometry and have relitively high fabricate skills you could go with a multi-link suspension wither with airbags, coils, coil overs or even 1/4 elliptical leafs.
