you may want to take a sawsall to those mud flaps before the rocks take them and some of the facia off.
and those side steps don't look like they'll hold up to too much beating but they'll save your rockers for the time being. you will be surprised at what a difference just a more aggressive tire will make. for now you'll want to avoid trails with rocky up-hills. i helped a guy in a new pickup truck on wheeler once that had spun his high performance street tires right down to the steel belts trying to get up the trail through the sharp loose rocks. a very expensive learning experiance for that guy.
