I have the OME kit. You pay more, but the onroad ride is top notch. I am not too mechanical, but was able to install the OME lift by myself. When I did it, I only installed the shocks, springs, and t-case drop. I added the body lift, motor lift, and adj track bars later - again all by myself.
With basic tools and a floor jack and perhaps a few rental tools from Autozone, you could easily do this yourself, save some $$, and put that $$ to some additional stuff on the Jeep, such as armor to protect from soCal rocks. With the potential Jeep being an 06, there should be little issue with rust, esp if in soCal. My soCal Jeep has not given me ONE problem when installing parts. No rust, and virtually no PB Blaster has been required. That is changing now that I'm in Alabama.
The I6 in the SE is nice and not an option on my 97 SE. However, you will still have the Dana 35 axle in the back. Going any larger than 33's could be a problem, especially if you offroad it. That is another thread though...
With the OME suspension lift and a body lift, I have about 4.5" of total lift and fit 33x12.5" tires nicely. Aggressive and good for a daily driver. Any bigger, and the daily driver-ness (is that a word?) becomes a bit tougher.
