I'm just trying to help you understand the forums a little better. We've all been there. I've asked questions before searching...got flamed, then learned to research as most answers are there. Then I'd ask questions that clarified my thought process or filled in a gap of missing info, etc. Yes, everyone loves talking shop about Jeeps but people do get irritated over the dead horse subjects like "how much lift" or "which shocks".
You just blasted a bunch of info that is easily searchable. For example, I don't own a JK but a VERY QUICK search on google showed your pitman arm nut needs to be torqued to 185 ft/lbs. That same site had an entire list of torque specs which was also one of your questions. According to google, that search took 0.24 seconds. I won't be a jerk and post the "here let me google that for you" link, but here is the link to your requested torque specs.
I'm not familiar with Skyjacker, but I'm sure they probably use a nylon locking nut. Loc-tite would work too.
Hope this helps.
