There is no Clustering available for the OSS only for the NE on RHEL.

I depends on what you plan to deploy if you are using the open source solution or the network edition are you planning using only the web interface or are people going to be on POP and IMAP, if you are on the NE are you going to use the outlook connector. In any case you'll need to do a multi-server...

You'll need to turn it off, and then disable it from startup.
Something like

/etc/init.d/exim stop

or

/etc/init.d/exim4 stop
Then to disable it at startup use chkconfig

POP can't do this POP can only see the Inbox, if you want to see the Junk folder you are going to have to use IMAP

You should be able to just run the install and install the MTA and AV/AS. You will probably want to disable the MTA service on the Mailstore/LDAP server as well. Might be a good idea to copy over all of your learnt spam as well.

If it helps search the wiki for a domain aliases. I recently implemented one myself.

I'm not sure what happened to it, but there use to talks about a Asteriks Zimlet, specifically it was supposed to allow for click-to-call. I'm not sure what other features where in it, maybe try to stir the pot and find out what has happened to it.

This has been discussed in the past. People have successfully upgraded ClamAV in the past without affecting Zimbra, I'm not sure if anyone has done this lately. Probably the best way to get this upgraded is to put a request into bugzilla and vote on it.

The easiest way may be to import from Outlook Express into Outlook then use the PST import wizard.
