Anything by Elizabeth Orna is worth looking at, but I seem to have missed mentioning the book that came out last year:
Orna, E. and Stevens, G. (2009) Managing information for research: Practical help in researching, writing and designing dissertations. 2nd edition. Open University Press. ISBN: 9780335221424
It is particularly strong in the area of information design and using information to communicate your ideas effectively, as well as managing information through the dissertation process.
