You can use postfix with dovecot without having to enable the DOVECOT
option -- as I recall, that's something to do with postfix using the
dovecot authentication mechanisms.

You only need OPENLDAP turned on for postfix if you want to use ldap
lookups.  (Well Duh!) For a stand-alone system without many users, ldap
is overkill, and you would generally be better off using lmdb or bdb
files instead (I prefer lmdb -- seems simpler and to have fewer overheads).

No.  Either you configure postfix to use dovecot's delivery agent, or
you make postfix speak LMTP to dovecot: from dovecot's perspective it
doesn't need to know anything about or do anything differently depending
on what MTA you're using.
