I was just victimized by someone posting my CC on a hacker site -

On Thursday I found out that someone had posted my name, address, cell phone number and a credit card number on a hacker's website and learned this by some good Samaritan  calling me.  I hindsight, after having gone through the process of notifying my CC company and getting fraud alerts put onto my credit thru the big three credit bureaus, I think this good Samaritan might have been a vendor who had been given the number and when it was declined he contacted me to let me know that someone was attempting charges on my card, but that is speculation on my part.
 
The important thing to me was that I learned about it within a few hours of the issue starting so that I could get on top of it and let the CC company know and hopefully **bleep** this in the bud before it gets bigger and uglier.
 
Since the announcement of the Sally Hack and also the big hack that was announced on the news that Federal Government sites were hacked, I'm not sure if it's all connected or not.
 
My question to all you very savvy computer folks is this:
 
Is there a site or organization where they investigate ID theft and cyber crime and go after the websites that carry this stolen information? 
 
The fellow who called me to let me now about my name and CC # being posted on line gave me the actual website where it was posted and I am not going to go onto it because if it is some sort of hacker clearinghouse, even with my WSA Complete I am afraid that I will pick up some kind of bug or worm or malware that will feed them additional personal information.
 
Also, do you have any suggestions about who else I should contact about this incident beyond the credit card company involved, the big three credit bureaus and notifying my bank to make sure that my savings is safe?
 
As you can imagine, this has been a very upsetting experience and I would rather go overboard protecting my personal information and my credit history rather than miss an opportunity to make sure that these people who do these things don't prosper from their actions.
 
Thank you all for letting me vent.    I still get that sinking, butterfly turmoil feel in my stomach as I type this!
