How to use CRM Database without the Frontend for Reporting Purpose using SSRS?

Hello,

Q1: We have no longer Dynamics CRM Frontend available, and CRM Database is exported in one of our local SQL Database Server, and now the business wants some reports from that database, the problem is most of columns are GUID and does not have textual data, is there any way I can get some reporting from this database?

Q2: The Business Users also created some custom database objects and its hard to find out which object is which? also doing a simple select on most of them is not giving the required results, is there any way I can Identify them and use them in my reports?

Thanks
