Good choice in Jeep model.
I am also on a tight budget. I started off with a 2" Budget Boost or BB for less than 150 dollars and a Body Lift or BL for around 120. Very easy to install alone. I kept the stock shocks and haven't had any problems. It's better to get new ones. Skyjacker Hydros are very recommended bang for buck and are now on sale buy 3 get one free. Tires are up to you. I run 33's. I have a pic in my sig.
My wife was not up to mods at first. She came around with time. HEHE.
Now I am working on a Rubicon Express or RE 3.5 superflex kit and eventually Long arms$$$$$$$$.
