Establishing Purim as a holiday for the generations, and Esther as a book to be read. Plus, including the Book of Esther in the canon of Tanakh. Also, how to give matanot la-evyonim and mishloach manot. And some narrative to flesh out the expected generosity in the above. Also, the story of Rabbah and Rabbi Zeira's excess on Purim that lead to a miracle and a refusal to rely on a miracle thereafter (perhaps getting drunk on Purim isn't such a good plan - or obligation). Also, a couple of mishnayot, distinguishing between key days, including Shabbat and Yom Kippur, and the punishments thereof. [Note: Some wonky audio at the beginning, but it (mostly) clears pretty quickly]
