The most detailed treatment of derivational forms is to be found in studies in Generative Morphology and Lexical Phonology. In extending your bibliography, look out for names such as Aronoff, Lieber, Siegel, Halle, Kiparsky, Mohanan. Overviews are given in the introductions by Carstairs-McCarthy (see [7]), Katamba (see [21]) and Spencer (see [35]). Traditional grammars, and reference works such as Marchand (see [27]), are a mine of information on facts of derivation in English. In preparing the report, take a look at the more formal discussion in the section on `Inflection: forms' and consider how to extend this to the description of derivational forms in terms of ID and QLP properties.
A list of derivational prefixes and suffixes, with their properties (orthography, phonology, stress etc.) should be made.
Check in the literature for the distinction between `Level 1' and `Level 2' affixes (in particular in Lexical Phonology).
