Looking for advice on where to place ISA 2006 Servers versus Active Directory DCs acting as DNS for several internet Domain Names

I am hosting about 20 Domain Names on IIS servers and I have 4 Active Directory
Domain Controllers listed as the Designated DNS for these Domain Names.

My network has public IP addresses that are used by these DNS Servers and
multiple IIS Web Sites where traffic gets routed based on the Domain Name and
Host Header value settings.

I am looking for advice on how to best insert ISA 2006 Servers in front of my
network using the public IP addresses with a dual homed configuration to route
traffic as appropriate onto my internal network.

Some questions I would like advice about are as follows:

Where should the DNS Servers be located?
Should I avoid promoting my ISA Servers to become Domain Controllers?
Will I need to place any of my DNS Servers/Domain Controllers on Public IP
Addresses?
To support SSL traffic, will I need a separate Public IP Address for each
distinct Domain Name?

Thanks for any help in providing answers to these questions!
