Good post! Might I suggest adding the training you get from game-world objects, as well as NPCs?

For instance, under the Feng entry you can also add that his opened Scroll and pile of junk in the corner (per 8) yield +1 Lore and +1 Lockpick respectively (sneak/after he is kicked out of town). Also, inside the Teron blacksmith's house, a diagram gives +1 Crafting (sneak 3, dex 7).
