I've never been to Baja but what might help:
-Specs or a list of mods you've already done to your Jeep
-Some better pics
It looks like you have a Sport so 6cyl, and a lift of some sort, and some larger tires. What about:
-Any motor/exhaust mods?
-What lift? Suspension? Body?
-Full size spare?
Not knowing much, I'd suggest making sure you have a full size spare and the proper tools to fix something should it break on the trail, and proper recovery points should you end up off trail? Basic Wranglers are extremely capable, so start with the basics and move on from there.
