There is no way to recover a patron's password as that would be a security risk. From the Control Room administrators can reset a user's password but cannot view it. In addition, users can reset their own password once the email system is functioning.
I don't think there's a way to see specific titles entered from the Control Room but I will check with people here because I know there were questions about that here during our winter reading program.
I'm sorry I don't have more details on the email problem for you, I will move that up on my priority list to troubleshoot.
