Looking at the layers I would like to propose that the copper layer be made not specific to copper, but a conductor. Some common alternatives are silver ink traces, embedded resistors, or even more exotics like ITO (used for touch screens).
For the footprints, They should have a routing keepout, different than a placement courtyard. That is don't rout on these layers in these regions. Pins and pads should have antipads that is when the pin goes through a plane this antipad is the area in the plane that is cut out for the pad on that layer. High speed signals often have the ground plane under the pad removed to minimize the capacitance/impedance change from the pad's greater area.
