Hey dude you don't have to spend $6,000 to add to your truck.
* Your tires look just fine to me, BFGs are more than enough, you don't need mud tires.
* You already have 4WD and could easily add a rear locker of some type for $600.
* You don't really need a front locker unless you are super hardcore and the vehicle should not be a daily driver.
* Rims can be found cheap, get a set of used for $300 and paint them.
* Supercharger is a waste of $ unless you are running a 4 banger or it came with the truck. My V6 has more than enough power, now that I added intake and exhaust.
I once considered selling my truck but I am sooo glad I didn't. I now have a used Camry as a daily driver.
