Yes, AFS uses Kerberos (v4) authentication.  Kerberos knows nothing
about SSH.

Sure, except there really isn't a kerberized NFS.  NFS will still be
unauthenticated.

By default AFS provides strong authentication.  As of OpenAFS 1.0.2
you can set a flag in the client to encrypt the filesystem data,
although the encryption is still relatively weak (it uses fcrypt).
Mostly this option will protect you from casual eavesdropping.  It
will not protect you against someone who wants to read your data, as
fcrypt isn't very strong.
