The Rambam's 13 Principles of Faith

We began watching this video today, starring Rabbi Mordechai Becher, in which he discusses the 13 Principles.  Please continue to watch through to the end (we watched the first 9 minutes or so already). Then, when you are finished watching, please answer the questions listed below, and share them with me via email. This assignment is due before class on Friday, Feb 27.
(The first 4 questions are contained in roughly minutes 10-20.  The next 4 are discussed in minutes 20-29, if you'd like to split up the assignment over the next 2 nights.)

1. Explain Rabbi Becher's analogy between what he terms "physical suicide" and "spiritual suicide", and how it pertains to the 13 Principles.
2. What were some of the prime objections to the Rambam's formulation of those Principles?
3. How do our beliefs about another individual affect the kind of relationship we can have with them?  What does this have to do with the 13 Principles?
4. Is it really accurate to refer to them as the Principles of Faith or Belief?  What did the Rambam really call them, in his original Arabic writings?  Why is the terminology so significant?
5. What ties the first 4 Principles together?  Briefly discuss a new concept that you learned about one of them.
6. What ties the next 5 together?  Briefly discuss a new concept that you learned about one of them.
7. What ties the last 4 together?  Briefly discuss a new concept that you learned about one of them.
8. Why are both proper beliefs/understandings AND proper actions necessary in Judaism?
