yeah, flip the rear links inside the sway bar and pay attention to which way you run your bolts, pretty much just keep things as far from the wheels as possible
For shocks, if you wanna save a few bucks, find a set of rubi take offs and use the extenders.
Rubi shocks are pretty darn good and can usually be had cheap or free
Thats the way to do it, I had my lift in hand before I took delivery too
some people don't like the idea of running a 12.50" on the stock rims because they're technically too narrow for the tire, BUT, I've had 35x12.50s on mine for a long time with no problems.
You also may rub without spacers using a 12.50
I'm not sure on that one because 1.5" spidertrax were one of my first mods.
