2 & 1. I keep the tarp in two sided mesh skins and pack it outside the back pack. The hammock, UQ,TQ, UQ protector, bug net or sock fit into a 30L compression sack, which fits into my Granite Gear Crown pack.
I keep the head end at the top of the compression sack, attach it to the tree sling, and it all comes out ready to hang. Don't have the heart to poke a hole in the bottom of the compression sack to make into a bishop bag.
