Well, I'm glad you like the end result, but I've opened up my own 0404 USB, and what I believe to be the stock headphone caps (the ones closest to the headphone out) are 220uF, not 22uF. 22uF is pretty small for headphone out decoupling, considering the relatively low impedance of most headphones.
Also, I think those five 47uF capacitors near the line out section serve as local power supply caps (someone who knows more about this stuff than I should probably confirm this). You'd probably do better with larger capacitance, low impedance caps like Panasonic FM/FC or Nichicon UHE/PW, rather than those gigantic Blackgates (although given their higher voltage, they probably have less impedance than the stock caps).
I completely agree that the stock wall wart is a joke (basically a cell phone charger), and replacement is definitely a great idea.
