A strong list of topics you have there, probably more than enough for your presentation. If I could jump on the coat tails of NCP, with site selection, you might want to mention a quick blurb that you should first find out if the usage of hammocks are legal in the area in which they are camping. Hate for a scouter to get to a state park in FL only to find out his hammock isn't welcomed in the main campgrounds. I'm sure there are several places that have similar rules.... however, this could reinforce the scout motto.
