Hi, John. If you are looking for primary sources, the most famous is Froissart’s “Chronicles,” a 14th-century work which provides a lot of information about the first half of the Hundred Years War.

Desmond Seward writes engaging works on medieval history. His book on the Hundred Years War is focused on the military and political stuff in a chronological format: http://www.amazon.com/gp/product/0140283617/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0140283617&linkCode=as2&tag=thewesttrad-20
If you want a book that is more topically organized, the volume on the war in the Cambridge Medieval Textbook series has dedicated sections to things like taxation: http://www.amazon.com/gp/product/0521319234/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0521319234&linkCode=as2&tag=thewesttrad-20
Rothbard discusses the politics of the 14th century very briefly in his History of Economic Thought as well.
