As far as getting a part, you can probably find a score in a major public (or university) library. Copy the parts from the score, using a musical composition program (either Sibelius or Finale). Sometimes these scores have mistakes, but it should be close enough for you to have something to practice. For Cinderella, this is a long a tedious undertaking.
