Hi,
I think you can read in the player guide something about the character creation, and if I have understood right what you are talking about, CP is \"creation points\", that is all the points you can use in the creation of your character. Every skill/background thing/whatever cost some of these points.
You can\'t change the look because it is not implemented yet. If with look you meant color of the eyes, of the hair, etc.etc.
