The best part about Cephalopod taxonomy is that some new student will look into it and it will all change.
The Fossil Coleoid Page and
The Fossil Nautiloid Page
have the latest (several) classification of coleoids and nautiloids, and a nit-picking page (I knew I read that before). I guess if there were more than just empty shells to study classification would be more stable.
