If you transfer one yes. Pikachu are NOT wild Pokemon in Black and White.
Once a legendary Pokemon has fainted it won't come back until you restart your game. This is assuming that you are talking about wild Pokemon and the ones that only appear once in the entire game.
Virizion doesn't cost anything to find it in the wild. If you are talking about the card, then it's value is 1.99$ or the Noble one is 13.99$.
