Spam Assassin is aviable on a per domain basis here - meaning you can turn it on for all E-mails on a domain. The one drawback is that you must log into webmail to view the filtered E-mails and clean them out.
Analog Stats are aviable for your domains by default. However you'll find easy to follow instructions in the wiki to install awstats.
I rather like the support system. There's two parts of it. If you've got a domain or service that's not working you can use their system to check and see if it's a server wide problem. If that's the case, then once you put in your E-mail address you'll get regular updates on their progress. If it doesn't seem to be a system wide problem then you can put in a 'tradidional' support ticket. All communication between you and support is saved in the panel - so even if you loose your E-mail of it you can find it there.
To top it off, there's dreamhoststatus.com where announcements and such are posted. You can subscribe to the rss feed for the page and know what's going on.
