A Master Ball

I'd say a dusk ball or a timer ball
You can't, you will need to trade them from Pokemon Diamond, Pearl or Platinum.
You will need to catch the three lake lengendary pokemon. (Mesprit, Uxie, Azelf).
Yes, you can, but it is confusing, not knowing which is which. It is easier catching Mespirit then attempting to catch Cresselia
you can go back and catch: -azelf -Uxie -Mesprit and also a SECOND -Palkia and a SECOND -Dialga
