On my Blue Thunder and TFS A460's I've just used 3 steps and never a problem. I also let them sit overnight after the first torque down then go back the next day and loosen then torque them one at time back to the 140.

50
90
140

that's what we do with our MLS stuff. get the engine warm, let it cool off, re-torque.

The torque value will be the same but you will get a more accurate reading because your not twisting the shank like you are with a bolt and the finer threads.

Same. I did it in three steps. Inner to outer, with the ARP lube. I used studs as well.
