I don't understand the decap network: why not go something more classical 10n, 0.1u and 4.7u, i.e. just a cap for each frequency range?

I think its to place them near each VCC to minimize effect of wire parasitics. Dave probably explains it better:

Pretty sure each cap is associated with a particular pin on the microcontroller.
