     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.
