IMHO yes.

No. Apache is a web server. Squid is a (web) proxy. Your client will use
the proxy to fetch the web page from any web server. The proxy stands
between the client and the web server.

No. You can select a parent cache (see "cache_peer" in the squid.conf)
which will be the ISA server in your case. In addition you can tell
Squid when to use the parent (see "always_direct" and "never_direct").
Only one proxy instance can do the authentication. IIRC any member of
the proxy chain can do that.

Hmmm. I used a package of my distribution (Debian). Is there no package
for yours?

I wish I had been that eloquent when first touching Linux. :)

Although off-topic I like to invest my two cents here. Disclaimers in
emails are not valid in a form of a contract. Tell that to your boss.
Plus a one-screen-large disclaimer is a little annoying.
