Kala, you probably never *will*. SE Ohio "theoretically" has two rattlers (timber and massassauga) but they are extremely rare; and "some few" copperheads but not very many, certainly not comparable to a couple states south of you.
So, relax :)

LOL, c'mon, it's FUN figuring out different alternatives for doing something :)
How big will it be, and what is your soil like. that's pretty much what determines whether just a floating slab is sufficient.
Pat
You can do either way in the oddjob, doesn't matter.
Definitely a real mixer is the best, of course! :)
No, you just tip it out. Can roll it up a plank to wherever it's going, then remove lid and there ya go.
The problem with wheelbarrow mixing IMO (if you're doing very much of it, anyhow is...
What k0xxx said.
There are quite a number of snakes that will vibrate the tailtip that way - it's been too long since my herp lab days, I couldn't give a reasonable list anymore, but I've only ever seen baby copperheads do it (not adults, and I've dealt with a lot of adult copperheads) whereas...
BTW, if you're mixing by hand, I highly recommend one of those "Oddjob" mixers or whatever they're called, it's like a smallish black plastic barrel with curved fins inside. The o-ring gasket on the lid is fiendishly evil but other than that I find this to be a much better way of mixing concrete...
Wow, reading Marianne's post made me realize, my post above is all based on the assumption that you were wanting to do a small shed on a floating slab with no actual foundation walls.... but you never actually said so and I may well have been entirely wrong in assuming that :P
If what you want...
I don't know, but am inclined to be cautious, because red maple leaves are poisonous to various livestock, obviously they're eating more of them than you would of maple seeds but I would still tend to steer clear of red maple because obviously it CAN be bad for the mammalian body.

If you go to the library, they will have books on building sheds, some of which deal with the slab issue; that would be my first suggestion, because pictures-and-book-chapter are worth more as an overview than anything we can say here.
To address your specific points, though:
Size the slab so...
My mother -- of pennsylvania dutch extraction, she considers parsley a major vegetable, not just an herb or garnish :P -- always had two years' worth of parsley plants going. In late winter she would start a few seeds (from the previous year's flowered-and-gone plants) but for the first half of...
Repeat, all I mean it is *weak* like most annuals are, i.e. does not penetrate mulch well at all. Bindweed is really pretty easy to mulch out. Not that it *is* an annual, which obviously it ain't. IME landscape fabric stops bindweed dead; cardboard or newspaper under mulch certainly do, and even...
Bindweed is different, it behaves more like an annual with a prodigious seedbank (and, indeed, bindweed tends to HAVE a prodigious seedbank). It does not fight hard when mulched. (edited to clarify, yes obviuosly it is a perennial, my point is that in terms of control you have to approach it...
Yeah, I happily leave some weeds alone (especially chickweed, my bestest friend b/c it is so sprawly yet innocuous) because they are good groundcover come August :)
Pat
And then try it in ground that is badly infested with vigorous perennial weeds such as quackgrass or (especially) Canada thistle.
Heh heh heh.
Works real well if main problem is just annual weeds (or nonspreading basically-harmless perennials like dandelions or plantain), and if you don't have...
