That all depends on what type of iPod you have. I recommend leaving it charge for at least 4 hours, as occasionally problems can arise if a brand new ipod is not fully charged. Given that you'll have the ipod for a while, charge overnight. Works best if you already have an ipod charging station or wall adaptor.
5 hours
It depends which iPod you have.

Yes. As long as the laptop is on and running, not in standby or hibernate, your iPod Touch will charge while plugged in.

No, the iPod will not charge if it is off. The iPod must be on for it to charge.
