Don't do that. Of all the mods you list, lockers will give the most benefits. I'd do lockers before anything else. This is an LJ? so you have 3.73s and a Dana 44. With 33s 3.73 is fine. If you want 35s you will likely want deeper gears, even as a DD.but I might have to forget about the lockers.
Do lockers and gearing if you need it number 1, since lockers are the best mod ever.
