Damn, how did I miss this one.
Call, don't email, call your local FBI office. They act upon different guidelines for this. Unfortunately, you have probably been the victim of an international scam and this might be a while before it come back to bite you in the ass.
You need to get proactive now, though. Don't settle with a simple wait and see attitude. Secondly, file a formal complaint with the FTC so that it gets on the record. You might also want to contact the SSA to look at getting a new SSN also.
Lastly, contact Ebay's FIT division and see if they will work with you to prevent anything from happening. They will have the most up to date information on the actions you might can take. This is how you can get a hold of them.
