For points 2 and 3, this is my understanding as well.
Regarding point 1, I thought that dhammacakkhu was a reference to the sotapatti phala rather than the magga (when one sees the Dhamma, ones becomes a sotāpanna)… but I would be interested to hear your views on this.
Regarding point 2, I just found this nice OP from Gabriel: Faith-Follower & Dhamma-Follower, which also confirms your point 2.
