Deeky, not all zoom lenses have variable aperture. A lot of them will keep the same aperture no matter what focal length you are shooting at. I have five zooms and only one has an aperture that changes as I rack the lens in and out.
The biggest problem with pushing your exposure in post processing with underexposed images is that it introduces much more noise into the image. The trick is getting the exposure as close to correct as possible and having a way to deal with that noise, be it a noise reduction program or the way you process and image. I find many times using curves and bringing the shadows down reduces noise since it is more noticeable in the dark areas.
