I recommend obtaining H.S. Harris' two volume 'Hegel's Ladder' (Hackett Publishing Company, 1997) on 'Phanomenologie des Geistes' itself, which is the most comprehensive study that has appeared. Essential reading for the study of Hegel's philosophy. Its price also takes a li'l Aufhebung, but well worth it.
Also worth getting is his 'Hegel: Phenomenology and System' (1995), which is a primer of sorts.
