    Is it meant to replace the body colored panel that is level with the hood
    when the headlight is down?  Or does it some how replace the lamp housing

Yes. It will be offered in both primer and painted forms. All you have
to do is unscrew the current panel and swap in the new one, it took me
about 30 seconds, unless the screws get rusted and stuck.

    air takeoff at the rear that connects into the existing miata air filter
    assembly?

I am not sure this is necessary, the objective here is to get cooler
air into the engine compartment, thus lowering the intake air temp, to
have additional ducting would alter the intake "ramming" (is this a
real word) effect, thus altering the torque characteristics, plus
making the ducting really smooth to keep the drag down is fairly hard
in that space. And lastly, the cost would seriously outweights the
benefit.
