I just had my blockchain.info wallet hacked, and my coins stolen.

Blockchain does not know how it happened and is investigating.

Here's what is known so far:

1) My identifier, pneumonic and password were all stored offline and separately.
2) My password was alphanumeric
3) They were never shared with anyone - EVER
4) I did not have my wallet setup so backups were sent to me by email
5) The wallet did not have an email address associated with it
6) Somehow, a hacker was able to gain access to my wallet and move my coins out - twice over 3 days (i did not realize what was happening and moved more coins into the wallet, which were moved out during a 2nd incursion)

I can see where the coins were sent to.

I know my tracing options are limited but I would like to try anyway.

How much can I learn from the address the coins were sent to?
Can I learn which company owns the wallet they were sent to? Blockchain? Bitstamp? Bitfog?
