Great post - I keep trying to think of additional things, but they all end up being about gear, so I think you've pretty well nailed it.

(OK, one example: if I'm only going to be out for a few days, then I might consider leaving all the beverages behind. My son pointed this out to me once before we left for a week-long trip. By drinking only water, I not only saved nearly a pound of tea bags, instant coffee, and cocoa mix, but I didn't need as much fuel, nor did I need the second pot or the mug - which, back in the days of stainless steel cookware, saved almost another pound.)
