Depends what your budget is.
If you have a couple grand lying around, lift it ! Rubicon Express, Teraflex, or OME are all reputable brands.
If you've got a grand lying around look into a rampage recovery front bumper and get yourself a nice winch (Engo seems to be popular, but everyone will recommend warn. It's like the apple or glock of the Jeep world... Good product... Obnoxious recommendations)
If you've got a couple hundred lying around, you could do a budget boost. Or you could drop a Sears Diehard Platinum battery in it.
If you've got a couple twenties lying around, grab a few cans of plastidip and go nuts (search around the googles/forum for ideas)
If you're as broke as most of us (from dumping all our money into mods) take the doors and top off and cruise around (depending on temp of course)
