Hi Deech,
1. Is there a way to output intermediate values of a calculation?
Debug.Trace.trace is what you want, its not quite as convenient (or safe) as cout, but its usually good enough. If you want to see more detail then Hat (http://www.haskell.org/hat) is probably what you want.
From a general design perspective should I concentrate on abstracting away just enough to solve the problem or solve the harder problem in the hoping of reusing that code to make life easier in the future?
Do what you need to do now, only abstract if it makes this current problem easier to solve. For example, by separating two phases of an algorithm, the code might become cleaner and more abstract. In this case, the code becoming cleaner is the thing to strive for, not more abstract. If however you know that you will need a function in the future, you might as well abstract now, but don't do it on the offchance that it will be useful.
