From the point of view of my theoretical understanding, it all fits together well (and Ajahn Brahm’s advice makes good sense) but again, I heartily wish you very happy studies.
As an aside though, you might be interested in a couple of talks on the hindrances Ajahn Brahm gave some time ago, that @musiko very kindly shared on the forum here within a full collection of talks from a retreat (may I take the opportunity to offer musiko my deep thanks for doing so).
