What is the best way to avoid downtime of the site? Should we have our old DNS point to the new server IP and make the Name Server changes at the same time? Should we stutter step all of the changes?

Have your new DNS server up and ready to go (make sure you test it) and then change your NS ips to point to the new DNS server(s). You'll want to keep the old one running for a couple of days. As long as the actual host ips haven't changed DNS caching shouldn't be a problem.

Second, we eventually want to weed out all two of the three domains, mainly to improve our actual IBL count and to avoid duplicate content issues of course. What is the best way to slowly get out from under those domains?
Is the best thing to do, point all three domains at the same content, then do a mod-rewrite or 301 redirect of the two domains we don't want to the one we do?

I'll answer these 2 together. Just have all the domains point to the same content. If you're using apache:
Code:
<VirtualHost www.domain1.com>
DocumentRoot /home/www/html
</VirtualHost>
<VirtualHost www.domain2.com>
DocumentRoot /home/www/html
</VirtualHost>
<VirtualHost www.domain3.com>
DocumentRoot /home/www/html
</VirtualHost>
No need to use a 301 redirect. 301 is only useful if you move content to another URL so the search engines (and users) will note the change. If you're simply going to weed out those domains then this is the simplest way.[/code]
