My first spot of advice would be to use unbound as your caching servers - it's 
stupendously bloody fast. It's free as in beer and free as in freedom, and 
also keeps up with cns which is neither (and costs an arm and a leg). Plus the 
developer is very responsive to bugs and features. unbound does the basics and 
does them well, there are aspects of DNS caching that it doesn't do (stuff 
that nobody bothers with anyway)

Don't use bind as your auth server unless you like pain. That thing is a pig, 
and a temperamental one at that. It's saving grace is that it's a reference 
implementation and can always be relied upon to be extremely RFC-compliant. We 
use it, not because we like it, but because it has one killer feature we 
absolutely need - ACLs

PowerDNS is a fine auth server. If it suits your needs I'd recommend you try 
it first. I don't know about it's DNSSEC abilities or feature roadmap - it's 
been a long time since I looked closely at it. Lack of ACLs is what killed 
PowerDNS for us, I still feel sad about that....
