b - no.
c - no.

also, if you dont have representation in the feed zone, pack 4 bottles, 2 on the bike and one in ea. of your side jersey pockets. I'd be more concerned over hydration/nutrition in a longer race in hot conditions such as this than I would about getting a flat tire.

Race well, that looks like a great event.
