1) do they have to discard twice as much since I have two out?'
2) is it "per card I draw" or "per instance of drawing"?

Four triggers are now available for you to put on the stack, each can target a different opponent.
As for the state-based-actions involved in this scenario I think everyone pretty much understands the you will lose the game if you resolve a Brainstorm with only 2 cards in your library and that you would not lose the game if a card said "Lose 3 life. Gain 3 life" while on 3 or less life.
The reasoning there is, as previously mentioned, because of the different wording of the state-based-actions. SBAs don't watch the game, they just periodically check things out to make sure everything is as it should be. The card draw is sort of an exception, but losing the game still happens later.
There is something in Magic that does watch the game very closely, these are called State-Triggers. Emperor Crocodile is a prime example of this. Beast Within, for example, could kill your only other creature and even though you would control 2 creatures when SBA's are checked, the state-trigger that the Crocodile has means you'll have to sacrifice your croc.
And, as Dreamer said, Oracle of Mul Daya's card-revealing ability is not a state-based-action (or a state-trigger), it is simply an ability that happens to work at (almost) all times.
