If you are devising this for a class of students, I think that being able to focus on the Hajj and how it caused another evolution in Malcolm's character would be where I would place the largest amount of focus. One of the most striking elements in Malcolm X's narrative is the idea of change. The idea of being able to explore different aspects of one's personality is something that makes the narrative uniquely different from other narratives and helps to bring a different and more fluid face to the Civil Rights Movement. Probing this area in the chapter would be great terrain to allow different ideas about the nature of change, how this comes about, and how this change is different or similar to the other changes that Malcolm has undergone throughout the work.
When you say "discussion questions," do you mean questions that will allow people to give their opinions on stuff? If so, there is no way there could really be answers to those questions.
To me, the most interesting discussion question that comes out of this chapter is "Does religion generally help people become more or less tolerant of other people?" In this chapter, Malcolm X becomes more tolerant because of religion. But it seems that religion often makes people feel less tolerant. But you can see how there's no right answer there.
You could also talk about racism. Is Malcolm right when he says that racism is caused by our history of oppressing black people? What causes racism anyway? Another unanswerable question.
