Asking the question from a position of almost total ignorance of both subjects, does someone know whether it would be possible to use genetic algorithms to help in the tuning of such parameters and filter coefficients?

Sad but true. I do have a good book ("Introduction to Data Compression") that describes the general approaches used in MP3 and other modern codecs but I suspect that a great deal of careful work must go into tuning the precise parameters and filter coefficients to make a really great codec.
