I would say "No" to #3 as well. While I don't have the rulebook in front of me, I don't believe the cards you play go to your discard pile until your turn is over. Once your turn ends, you don't get to use the effect of the Event as it says specifically "during your turn". Even if you did get the card back this way, you would not be able to play it as you've already ended your turn.
I have to agree. At that point your turn is over and this event will have no effect.
