You are not using your cameras lightmeter correctly. Too dark means you are underexposing the scene and too light indicates overexposure. Here is a link that will show you how to balance ISO, shutter speed and lens aperture http://camerasim.com/camera-simulator/ As far as auto-focus is concerned, make sure that the lens is set to auto-focus.

Contacts are indeed a problem. The lens may be set to the smallest aperture size (largest f/number). If it's an old lens, then there may be compatibility issues with the camera. It's not uncommon with Canon. If it's a new lens on a relatively new dSLR then bring both to the service center and let them figure it out.
