Also how do you go about doing your homework on pieces you're working on?
Sorry I can't help you with this specific piece -- as to the other question, it depends on a few things. If I've never played anything by a composer before (this week I started my first Schumann) I'll go to the library and read about them:
Lives of the Great Composers by Harold Schonberg has good short biographies. This helps me get into the composer's head, understand their culture, their life, things like that. With Schumann, the whole Florestan/Eusebius thing threw me a bit.
Of course I try to get a recording or two or three, and try to read about when/where/why the piece was composed. Also I go to Dolmetsch's online music dictionary and look up any unfamiliar Italian words in the score itself (like "mancando").
Then I practice my butt off.
