I would generally second the recommendations to avoid supplements before 1L, but if you're going to do it anyway or just want to figure out which to buy, I'd say that I've found the ones in your list pretty helpful. It does vary by prof a bit, but mostly in that I've found some profs' styles to be completely incompatible with supplements (e.g. I hear Dressler is great for Crim, but it seems like it'd do nothing for my Crim class. If anyone here in my section sees this and disagrees, pleeeeease let me know. haha) It would have been annoying/confusing/maybe harmful to have read that before getting to this class.
The Glannon Civ Pro E&E might not actually be a bad thing to flip through if you really, really, really want to start reading law school supplements. I found it really simplified relative to what you'll actually cover in class, and it reads nicely. Chirelstein on Contracts wouldn't be bad either -- it's a quick read and not too in depth (but very helpful for review). I'd avoid reading for Property before law school starts -- topics really seem to vary by profs, and I think even the best supplement varies (I'd just go with whatever your prof recommends or is keyed to your casebook -- no need to use both Emanuel's and Gilbert's; I don't think there wasn't really a difference in quality or content between them). Oh and, FWIW, I found that the Emanuel's Civ Pro outline was more useful than the Glannon E&E once you're actually outlining and/or clarifying your knowledge.
Mostly, I'd just second the recommendations to read Getting to Maybe (I read this before law school and actually found it useful), A Civil Action (just a good book and the nerdy I'm-going-to-law-school setting makes it better), and books that are completely unrelated to law school.
