I likewise wish to withdraw my remaining USD balance. Since you said all the USD balances are okay and you have all the account records, it should be no problem for you to re-enable enough parts of the site for us to log in and initiate ACH withdrawals. Please don't hold our USD hostage; that would very quickly make you look like the bad guy.
I agree. I hope you can recover from this and re-emerge as a viable exchange. There is very little you can do right now and holding onto our USD will not help get the stolen bitcoins back. Making it difficult or a PITA for us to recover our USD, however will be detrimental to the Bitfloor brand and good will that you have earned in the past.
If you could reenable the site so we can make withdrawal requests that would be nice. I'd also like to double check if I had a bitcoin balance on your site. I'm pretty sure I don't, but need to log on to verify.
Rebuilding your exchange will probably take months. Delaying our USD withdrawals will not speed that up any.
