Your outline sounds good to me. I think of the first three of the four stages (Body, Feelings, Mind) as tending to deepen Jhana. I think of the last stage(dhammas) as tending more towards insight. In the contemplation of dhammas I let go of effort to calm, collect, and energize my mind and allow for much more of a just sit and observe approach. I do this regardless of the degree of calm I have been able to bring about up to that point.
"Beautifully taught is the Lord's Dhamma, immediately apparent, timeless, of the nature of a personal invitation, progressive, to be attained by the wise, each for himself." Anguttara Nikaya V.332
