You are correct.
Black=Hot
White=Neutral
Green=Ground

Answers:    You own it right so far.

The black (hot) wire other goes to the brass fitting on the plug and the white telecommunication goes to the silver fitting and the green go to the green ground fitting.

This determines the polarity of the plug.
