Completed USB portion of layout
Use 33pF caps on crystal instead of 22pF in order to more closely match the crystal's load capacitance
Much closer to finished layout.

Redid decoupling caps so that both ends connect directly to IC devices.
Changed crystal oscillator caps to 33pF
More layout work.

Rearranged a couple of pieces to reduce space (still working on that) and wired up more areas, including the ISP connector.
