Some help for your journey, should you ask for it:
Books:
FINNEGANS WAKE, James Joyce, Oxford World's Classics edition: This edition is one of the best. It has a helpful Introduction as well as a Chapter-by-Chapter Outline, Notes on the Text, and a Chronology of James Joyce. All very important to understanding the Wake. It also follows the 1939 pagination which most if not all reference sources use.
