With v1.x yes, with v2.x no (because in v2.x it's again in a separate process to allow support for multiple clients per process).

Yes.

Username yes, password no. I guess you could modify Dovecot code so PAM code saves the password and passes it to mail process.

v1.x or v2.x? v1.x is really simple, v2.x needs more work.

How are mails delivered then anyway? Doesn't that process also need some kerberos ticket?
