Both wikis were originally written by <ahem> me /<ahem> with a lot of 
help from others. A SQL storage for bayes will help you.. since now more 
than one server is contributing to both spam and ham learning. For SQL 
bayes learning is fast and so is expiry.. plus the SA devs recommend it 
as the preferred storage back-end.

For the caching nameserver a low-end box with a gig (or 2) ram thrown in 
and good connectivity would be great. You could also simply install the 
caching-nameserver RPM if you are on redhat/centos..
