Fighting Styles
Kick boxing is probably a good pick for beginners, followed by Streetfighting then either Wrestling or Submission as a third choice. Martial Arts sounds neat, but is fairly hard to KO people without a blazing grapple or an environmental-based throw (like head into a TV set).

Defeating Crow
Get him near the window. Bang his head on the window three times and he will fall out.
