Yes, have someone show you how to visualize it on the DG or HSI. Once you "see" it, it becomes a lot easier.
Number 3 is what confuses. The radial is what they'll give you, but that doesn't mean it's the same as the inbound course. I find that is a common struggle in understanding holds - at least it was for me. You must determine the inbound course to the fix.
Why they don't just give you an inbound course and be done with all the rest is beyond me. Be much easier. "Hold at blabla Fix, course 180, right or left hand turns" would eliminate the need for all the other BS like cardinal direction etc.
