Tyler, Any lift over 4 inches will cost a pretty penny, not only that any long arm kit is going to require you to cut off the factory control arms and mounts to give you room to weld in the new mounts farther back. A good 4-6 inch lift lit will around 3K$ and up depending on what the kit comes with. Not only will you need the lift kit but you also have to factor in shocks, brake line extensions and new drive lines. You will not need a Slip Yoke Eliminator kit because the Rubicons come with one already in the form of a flange type rear drive shaft.
With a limited budget your best bet is going in stages, like starting off with a 1 inch body lift and drive that for a while as you get use to your jeep. Save up for this big lift, till you can drop the big bucks down on a lift you can afford and with the options you want.
The factory equipped Rubicon is a highly capable machine right off the show room floor, with Factory Dana 44's front and rear, 4:1 reduction in the OR241 transfer case, and 4.0 motor your Rubicon will take you places that other stock jeep could only dream about.
This should allow you plenty of time to research all the lift MFG's out there and help you make a better choice later on.
Hold off buying things like a winch or other things till you find your self getting stuck and have a need for them. Half the fun of getting stuck is finding your own skills of getting unstuck. Personally I waited 8 years till I bought a high dollar hood ornament (winch) and found that I learned a lot more learning how to get my jeep unstuck using things like a hi-lift jack, strap and a good olé shovel. And the memories were better, because I rescued myself and now know exactly what my jeep is capable of, and what other stock or near stock jeep can and can not do.
