Debian (and Canonical, and Redhat, …) support is independent from
upstream support. Samba 3.x in Wheezy/Ubuntu LTS/… will continue being
supported by their distributors until they're EOL. So there's no
immediate need to update everything.

No idea, we migrated from NT4 to an AD straight away.

Samba 4 doesn't support external LDAP backends any more, at least when
running as AD. As far as I know you'd need to set up Kerberos trust
between them and use different realms.
