Don't get hung up on a height. You can run narrow 33's with no real lift. If you want a wider 33, you only need a little.
BJ spacers should free up travel and kill idler arms, they alone should not be a source of lift.
If you want to lift it because you like monkeying with the truck, then do whatever you want.
If you want to wheel it, get that on 33's and lock it. Less lift is always better.
