For information I'd try www.sparknotes.com and www.gradesaver.com (ClassicNotes) that will give you the lowdown on the play, probably by each act...not to mention character summaries.
As for lighting design, there was only one forumer who did LD for their IP in 2004 and that was Turbulance. PM or Email me if you want to get in contact with him as we're friends and he doesn't often come on BOS anymore.
