Whoa, theory attack!
I wanted to comment on one thing:
I think you have a more Schenkerian view towards analysis than I do, Gario. I'm personally interested in pulling out all those vertical chords, as opposed to collapsing harmony into functional chunks. I find it too reductive to gloss over harmonic subtlety in favor of a broader analysis -- those intermediate chords are where all the fun is for me! If I lose some of the big-picture harmonic schematic in the process, I'm okay with that; I much prefer to drill down to the details.
Hopefully that explains a bit more of where I'm coming from with these. Thanks again for the comments!
