You want to set redistribute default route to if installed on your BGP routers and never everywhere else. No should be selected for redistributing all other routes except OSPF. Then go into networks and explicitly add what you want advertised. For example, if you do PPPoE, you don't want a advertise a bunch of /32s but just the netblock actually on the router.
Then setup each interface manually.
