Default Focal Length

There are 2 parts to this question:

1. With a smaller CMOS with a focal lenght adjustment of 1.6 (like on the Canon EOS D10), what does this do to the images, quality and size?

1a. Does this adjustment mean that if I am using a 50mm prime, that 50mm is optical and the other 30mm is digital?

50mm x 1.6 = effective 80mm

2. Is the focal length of the lens recoreded on the image when it's stored? I know time/date/aperture/film speed are, but what about the lens I was using?
