You would be able to limit the incoming connections on the isa to those
coming from the internal PIX.

I would second the idea of putting a sql server in the dmz with the web
server and replicate your data to the dmz sql server.  That's the safest
for your internal network.  That way you would only need outgoing
connections through the firewall and would not need to allow incoming
connections into your internal network.

Well, it will add an "additional layer of complexity," but only in
regard to your network topology.  To be pedantic, Server Publishing 1433
won't "proxy"
anything... I will just pass the traffic along transparently (unless the
back-end is a different subnet, in which case it will be NAT'd, but
still, no difference.)
