My tax preparer sent a copy of my tax return documents to the wrong email address. What now?

I mean, sure, I immediately hit the gym and deleted my Facebook. But, besides holding tight and hoping for the best, is there anything I should do to prevent problems?

He sent the return by email to me and my wife and my wife's email address was incorrect. I checked and the account already exists for that address, so no luck on that.

The return has our SSNs, address and bank account information. We're thinking of switching bank account as soon as the refund hits the account.

Any opinions on the identity theft "insurance" and stuff like that?

I already check our credit reports every 4 months (thanks to http://www.ftc.gov/bcp/edu/microsites/freereports/index.shtml).

Thanks!
