I don't understand why you're not raiseing the flop. Are you taking one off to make sure it's not a scare card and to set yourself up for a raise on the turn? If that is your reasoning then that seems good. If you're just trying to build a big pot then your reasoning is wrong because you already have a big pot and you need to protect your hand rather than building a big pot.

Also I don't believe you can count some of your opponent's outs as already folded or in other people's hands because then you have to also up their outs for ever card that is in people hand's that isn't what they are trying to hit.

I would definitely bet the river.
