A couple sources to check out:

The Census Bureau's 2007 Governments Integrated Directory. Specify a state -- then narrow by agency type or county if desired -- and it'll give you a big HTML table of agencies, their addresses (lots of P.O. boxes), and some URLs. Since 2007 is long ago in Internet time, a better source for URLs might be...

The Small Business Administration's U.S. City and County Web Data (data.gov entry), released in January 2010, will return URLs of city and county governments, in XML or JSON -- so formatted for machines to read not humans, but you can make sense of it.

As far as I know, a nice, complete, up-to-date gov't directory with phone numbers and official contacts doesn't exist. Some folks would like to create one, calling it DemocracyMap. You can find a few more datasets in their project notes, where I found both the above links. But those are your best bets.

If you ever compile some of this data yourself, be sure to share! :)

I have not found a single, comprehensive listing anywhere in the format you're looking for. This index, published by BRB Publications, is useful, but it's a drill-down page.

Have you tried looking for government office information in spreadsheets and PDFs, like so? While it'll be labor intensive to get to the good stuff, it's another way to start getting the information you're looking for.

You might pick the brains of Sunlight Labs, "part of the Sunlight Foundation a non-profit, non partisan Washington, DC based organization focused on digitization of government data and making tools and websites to make it easily accessible."
