I have recently bought a Cisco ASA 5505 for my small business, I was initially led to believe this device could do some limited website filtering that we would need. (one list of unrestricted, and a second for email only) Since it has come to my attention that it may not be able to do this what equipment or software will I need to make this happen?

If you want total control, and have a spare machine to use as a server, the combination of Squid and SquidGuard is a pretty versatile solution.
