The boy character in Black and White, according to Bulbapedia, is named Touya. He is usually referred to as 'Black', though. The female character (also according to Bulbapedia) is named Touko. She is usually called 'White'.
These might just be names for other languages and not for English but that's all I know so far. I hope that this helped.

The differences I know so far, is that there are going to be a couple new pokemon. I think the names of them are Keldeo, Meloetta, and Genesect. They are also bringing back some pokemon from older regions. Thats all I know so far. :D
Yes, evolution is still available in Pokemon Black and White, although like most generations, some of the new Pokemon introduced have no evolutions and therefore will not evolve, such as Audino and Durant.
In black 2 you get Zekrom, Black Kyurem, Latios, Electibuzz and get to go to Back City. I white 2 you get Reshiram, White Kyurem, latias, Braviary and get to go to White Forest. In Black City you can vs high level Pokemon trainers and buy more items and in white Forest you can catch some Pokemon that you can't catch in Black 2. The rest of the game is the exact same so you decide witch one is better.
