You can't catch Dialga in Pokemon White. After you beat the the Elite 4, you can use the PokeTransfer to receive a Dialga from Pokemon Diamond, or Platnium.
Dialga and Palkia. You have to battle the Galactic Leader and then catch Giratina. They will be waiting at the spot where you catch Dialga in Pokemon Diamond. You will battle Dialga and then Palkia, both of them being at lvl 70. Be sure to bring some ultra balls or master balls if you have any. Hope this helps!
