My clever husband made a couple of good points re: the list which I thought I should mention.
First, as regards canisters of propane fuel: he pointed out that with an adapter and a bit of hose, anything that runs off little Coleman canisters can be run off the big boys, which are 1. cheaper, 2. more convenient because you don't have to switch them out midway through dinner, and 3. exchangeable and therefore more environmentally friendly. Suiting actions to words, we bought said adapter, which should be easy to find, since ours came from Walmart on the Coleman shelves.
Second, he added WD-40 to the handy-man section of the list. That's a pretty solid addition.
I'm feeling pretty good, because after a little shopping yesterday we now have a good stock in hand of most of the list. Since the vast majority of that is stuff we use anyway, the main effect is that we've saved money by buying the value-sized packaging and saved hassle by not having to go to the store for any of this stuff any time soon. If that's all this round of "stocking up" ever comes to, then I am well satisfied.
