  1. As Rob says "define live", but yes, in principle there's no problems doing this.

  2. The Arduino has servo libraries so all you really need is a connection to the servo's control wire.

Question, the servo may be 12v but does it need 12v on the control wire?

If so you need to level shift your Arduino output with a transistor, if not you may be able to drive it directly.
