^ I just want to say that I normally hate that phrase, but I think it's used appropriately there. It pisses me off when people use it to essentially mean "a Wizard did it." However, chronologically is not usually the best way to look at things in Doctor Who and that's generally the point of that quote. Effect doesn't follow cause.
That being said, Prisoner Zero's quote, according to the internet, is "The universe is cracked, the Pandorica will open and silence will fall," so it appears to be the order you want. I had to look it up because I more clearly remembered the "silence will fall when the question is asked." I think that one is true from the Doctor's perspective (if the "it was my silence" thing is correct).
