the camera meter works differently from an external meter. It looks through the lens and sees the available light in order to give you the reading. that's why the meter doesn't appear to over or underexpose because of different lens transmission rates. External meters read either the reflected or the incidence light available and give an approximation of the light reading based on how most lenses perform at certain apertures.
just remember that meters are not gods, they can be fooled too ;)

no, usually the amount of light you get from light readings is pretty damn close. Just remember to add however many stops of light you need to compensate for any shortcomings of the lens itself. Think of it as mentally applying exposure compensation ;)

aperture is not a direct measure of light transmission, that would be a T-stop. Just cause 2 lenses have the same aperture does not mean they can transmit the same amount of light, since aperture is just a ratio of the focal length to the aperture opening thingy
