First I wouold invest in door locks that can keep people from steeling your doors right off the hinges. Then I would do as I have always done with my yj in the summer ( I drop the top and doors all summer.) Get a thick chain and a big masterlock padlock, keep it right by your seat on the drivers side. When you get out, just wrap it around the clutch and brake pedal tighly. It's pretty hard to remain inconspicuus with a large pair of bolt cutters trying to break something like that; too much attention for the average thief!
