I am running Dovecot and wanted to make sure that to disable POP3 access on the MDA is as simple as removing the POP lines:

protocols = imap imaps pop3 pop3s imap_listen = * pop3_listen = * imaps_listen = * pop3s_listen = *

Do I need to modify anything else or am I looking in the totally wrong section

Remove "pop3 pop3s" from the protocols list, that is enough. You can even leave the _listen lines for pop3. (But those are just the defaults, so you could remove them anyway.)
