First..do a search. The answers are there.

I'm waiting for my OME 912 springs to arrive. (Don't order throught Rocky Road off road in Colorado- say one day, then the next and so on. I've been waiting for weeks)

Anyhow, from what I have read here, you do not need all that stuff. However, Swordy did mention something about the Bumpstops. You may want to ask him.

Again, do a search..ALL the answers are there.
