Regarding connecting Crystal to the LEM, have you seen this KB?

I'm not sure the information you're asking about (Office, Department, Manager) is going to be included in the change messages logged in AD. Do you see this information in the Event Viewer for the Security log? If not, there's no way the LEM is going to be aware of that information to present it in reports.
