I finally read the relevant wiki's. Learned 2 things: 1) The scratches on the plastic layer are not relevant, because it has to come off anyway. 2) I should have used a cutting wire to separate the layers. All the other information was really already provided by you.
So II'll have to find a fitting capacitive touchscreen and get it to work with the Note Pro. A resistive won't work be cause it will interfere with the Wacom layer.
