When you are returning home after visiting Hong Kong, and after getting your boarding pass, do you still need to show your boarding pass to the Hong Kong Immigration officer at the passport control, or you can just show them your valid passport and the other portion of your arrival form given back to you to get your exit stamp?

You need to show your boarding pass. I believe that you also need to exit on the same passport that you used to enter HK.
