as for every beginner which tries to grok type classes, i recommend
you to read http://haskell.org/haskellwiki/OOP_vs_type_classes and
especially papers mentioned there in References section

also, i recommend you to subscribe to ru_declarative and ru_lambda
LiveJournal communities and read them back - several month ago i've
placed there simple explanation of differences between C++ templates,
OOP classes and Haskell type classes
