Right.

Obviously.

I would definitely recommend a local-only address for the local services.

He /could/ do that but you haven't said why he should.  If he wants his DNS/DHCP server connected to the outside internet, I would recommend he get two ethernet cards, eth0 and eth1, then configure dnsmasq to only serve on only the local interface.  Note that this doesn't require any DNS-specific configurations.  It is inherently simple and secure.

I think he wants name resolution for all local hosts (why not?).

Nowhere do you say why the complexity of BIND is necessary.  He would be served very well (no pun intended) with a far simpler DNS implementation.
