1) Why exactly do you want to be a "Linux power user"? That doesn't sound like a real goal; you might want to elaborate. Why not ? A lot of us like to learn just for the sake of learning. I say becoming a Linux power user is a worthy goal in itself. I agree with your point 2), it's fair easier to dive in and try it, rather than ask in forums if you should do it. It's not like it's going to cost you anything. Just download Virtual Box and do it.
