Right; if you want zeroconf on the adapter you set specify "AutoIP" mode
in the connection editor.

I'm not sure I understand how DHCP plays into your network setup.
AFAIK, with PPPoE, NM should be starting PPPoE on your NIC and PPP will
return the IP address that you need to use.  There shouldn't be any DHCP
going on when using PPPoE.

You can set up a real PPPoE connection from the "DSL" tab of the
connection editor (/usr/bin/nm-connection-editor, or right-click the
applet's icon and choose "Edit Connections...").
