ISA vs. Firewall

I'm starting to explore ISA so my questions may be off.

I'm sure many of you are familiar with WatchGuard boxes (X500, X700, for
example). Is it safe to equate ISA with firewalls ? If not, never mind my
question. If yes, where is ISA ? A high-end firewall ? Or, somewhere in
the middle ?

Is there a server naming convention when setting up ISA ? Does it have to
be FQDN ?

If ISA sits behind a firewall but is placed on DMZ, is it better off to get
rid of the firewall altogether ?

Thanks
Steve
