The Lords Report are reports of the House of Lords. See their website if you wish to familize youself with who they are and what they do. 

 As to your other questions, I do not even understand your questions so I do not know how to give you the answers. The narrative was presented as you read it by historians and much of it has been reprinted in the updated DNB at Oxford. It seems quite clear to me. If you do not understand it perhaps a basic reading of medieval historical material and its terminology might help. Hope this answered most of your questions. Good Luck!
