One of the best volumes on this, IMO, is Covenant, Justification and Pastoral Ministry (P&R), edited by R. Scott Clark. It has an intro. discussing how the debate got to where it is. The said intro. is quite short, so it leaves out a lot, but it would certainly give at least a partial answer to some of your questions (like the relationship the FV has to the NPP and Norman Shepherd) and you could find more info by checking out some of the books cited in the footnotes. The book is tough at points, but well worth the effort. I think it's actually written quite simply, considering the complexity of the issue. Anyway, that's my recommendation.

"The devil’s singing over me An age old song
That I am cursed and gone astray
Singing the first verse so conveniently
He’s forgotten the refrain
Jesus saves!" (Shane Barnard, Embracing Accusation)
