Welcome to TUJ! As Matt said you are headed to the right direction and Id also suggest going with the JBA rear springs 4" to avoid spacer stacking, Ill eventually be going this route.. You may also want to add an adjustable rear track bar, when lifting the axle will be roughly .5" off to drivers side, track bar is cheap $135? As far as wheels, let Matt and Adam help you with this I get confused to and it can be frustrating, but they seem to have a great grasp on this! Im running 265/70 Goodyear MTRs on stock chrome clads but running 1.5" spidertraxx spacers with pinch weld mod done, very easy to do, and Im very pleased with these tires. For MTs their road manners are great and off road, well they are beasts! What type of skid plates did your rig come with, if any? May want to consider those as well to protect the undercarrage..
