Okay...on a JK like yours, here's the info you need to know about lift.
Because you have a manual, (no auto tranny crossmember to tear the boot on the CV joint) you are probably fine with 2 or 2.5 inch lift with regards to your front driveshaft. Your rear driveshaft will start to see some premature wear, but if you stick to 2 inches of lift, I'd say don't bother worrying about it. If you get a 3 inch or larger lift on your two door, you may be significantly shortening the life of your rear driveshaft...but an upgraded aftermarket driveshaft will solve that issue.
You could probably stick a set of 33's on the wheels that you've picked (good taste by the way) without a lift and be fine on-road...but they will rub if you're offroad. A 2 inch spacer lift would probably get rid of that little bit of rub. "Spacer" lift or "BB" or "Budget Boost" refers to a suspension lift that "lengthens" the stock coil springs by placing a puck between the spring and the spring mount. Some folks will tell you that this will overcompress your stock springs and eventually cause them to sag, but I can't offer any actual first hand knowledge on that.
A "budget boost" make your Jeep a little taller without spending too much money. The other nice thing about a 2" budget boost is that it doesn't change your stock suspension geometry all that much, so your on-road handling will stay reasonable without a lot of other changes (control arms, adjustable track bars, etc.) That said, understand that ANY mod you make will affect the rest of your Jeep, and any lift or larger tires will put extra stress on your rig.
The next step up from that would be a coil spring lift. This will make your Jeep taller and offer more room to fit bigger tires, and it will also increases the amount of suspension travel you have available to deal with obstacles off-road. The difference in performance between a 2.5" budget boost and a
good 3 inch coil lift is night and day once you are off the pavement. Then again, so is the cost. A budget boost can be had for $500 or maybe even less if you cut corners. A good coil kit (and all the associated parts to let it perform to it's potential) will probably run you between two and three thousand.
The most important advice that I can give is to not modify anything for off-road until you take your Jeep offroad. Get some reasonable AT or MT tires (sometimes you can Find JK Rubicon take-offs for a greeat price)_, make sure you have front and rear tow points, maybe add a CB...and then wheel it for a year. See what other people have done to their rigs, see what the REAL performance is on obstacles on the trail, and then make up your mind.
I had my Jeep for over a year before I lifted it, almost a year and a half before I went to larger tires, and I'm glad that I waited as long as I did. I ended up with a lift, mods, and tires that work well for me both on and off the road...and the things that I thought I wanted to buy when I first got my Jeep would not have worked as well for me...and I probably would have spent twice as much replacing them by now.
