With that setup, if you wish to do content filtering, I would suggest you add a proxy.

Squid + squidguard, dandguardian, privoxy.

Of the 3, IMO, privoxy is easiest to learn, but squid has more features (and is thus more complex to learn, the more features you use, the more complex squid becomes to use).

Dansguardian will piggyback with squid or privoxy. The default content filtering will need to be reviewed and perhaps modified, which is IMO more time consuming then privoxy.
