Getting it into your server is a piece of cake using some of the tools that others have put together.  I believe I used this. 

It took about 10 minutes time from finding the census bureau data to having it downloaded and imported onto my local database.  Using simple select queries you can get maps of all the states, or even the counties within a state.  That said, I believe the counties or zip codes I downloaded were a bit outdated, so they’re not perfect; but they’ll get you a long way down the path.

After importing the data, here’s what Florida looks like:
