I understand your pain, watching through most of the Gnomon vids I've noticed many gaps. I've had to combine multiple DVDs to accomplish what I needed.
If you want to learn character modeling, just learn ZBrush. I'd highly suggest 3 of the vids here on Gnomon, but of course there are tons of documented material on these things.
Intro to Zbrush
Character Modeling for Next Gen Games
Digital Sculpting the Human Anatomy with Zac Petroc (anything by Zac is king)
With those 3, I guarantee you will learn 3d chara modeling however there are gaps.
Gap 1: They don't quite explain how to add clothes from Maya in for the Character Modeling for Next Gen Games... but it is simple. You export a low .obj of your anatomy from ZBrush into maya, model in a super low poly shoe that fits your chara. Import back in and add as a subtool. Continue sculpting.
Gap 2: This is the major one. Topology. There is an Overview of Topology on Gnomon, but it doesn't solve the major complication with retopo, which is the theory. Its hard to learn how to retopo, but I'd highly suggest these free tutorials
