YaRET is a Perl script that automates the ripping, normalization, and encoding of CDs. It supports CDDB very well via the Perl Audio::CD module, and also can work with your favorite ripper/normalizer/encoder (e.g., cdparanoia, cdda2wav, normalize, etc.) It supports useful features like multiple concurrent encoders and an easy to use configuration file that lets you customize YaRET to your taste (such as file naming based on the CDDB information).
