You will need some knowledge of economics, and you will receive basic training in quantitative methods. Difficult??? Yes, but you will survive. History? you better forget it.
Some people believe that economic history is related to history, wrong. It is a just part of economics, case studies of how economic theory can be applied, although there are always more historical courses.
BTW I have seen your reading list post, I have to sleep, tomorrow I can tell you more about what I would read.
