currency trading models

Can you tell me a little bit about the IMF and World Bank?

What is the purpose of each, and how are they different?
How effective are they?
Why can’t this be handled under one organization?
What is the likelyhood of a Bretton Woods II, and will these organizations survive?
What sort of organization do economists, politicians, and the public think should regulate international trade…will it be a more European-looking system, and if so, what does the EU have to offer to America in exchange for adopting its policies as a new worldwide model?
While the dollar remain the reserve currency?
