Update on the situation. Summary: some non-US credit-card information from 2007 compromised. No US customer credit-card information compromised. Hashed passwords compromised, no plaintext compromise. Publicly-known information compromised.
I'm going to change my password once the systems come back up, just in case the hash isn't as one-way as they thought, and keep an eye on my credit card for unusual activity just in case. Beyond that I don't see any reason to worry.
