Re: What to pass on?
Sort of a confusing question. I think the most important thing to pass on is.... everything. I can think of no reason to do otherwise. In teaching, what you teach next is whatever works best in the progression. Prioritizing the importance of each thought or idea as though you will only get the chance to give one more lesson is fatalistic. The study of Aikido is a lifetime pursuit, so it follows that the teaching of Aikido is that as well. JMHO.
