Great breakdown. I took a quick look at the HTML, and this is what I got from the div ids, listed spatially:

Mixer Section:

  "mastervol"             "moog-volume2"

                          "moog-volume1"

                          "moog-volume3"

Oscillators Section:

  "moog-osc2-rg"          "moog-osc2-pb"          "moog-osc2-wf"

  "moog-osc1-rg"                                  "moog-osc1-wf"

  "moog-osc3-rg"          "moog-osc3-pb"          "moog-osc3-wf"

Filter Section:

  "cutoff"                 "attacktime"

  "moog-glide"             "decaytime"

  "contouramount"          "sustainlevel"

Envelope Section:

  "moog-loudness-attack"

  "moog-loudness-decay"

  "moog-loudness-sustain"

It looks like that confirms pretty much everything you described. For the filters, it looks like the filters section of the Minimoog panel, but rearranged a bit in order to form an "O."
