As Peter says, you seem to have things well in hand. Only thing I could possibly suggest would be to hook up the 5.1 analog outputs of the Oppo to your controller in order to take advantage of the Oppo's ability to play DVD-A discs.
It is possible, however, that you aren't interested high resolution audio, and the relatively expensive DVD-A discs that provide it. I'm so hooked on the damned things (DVD-A
AND SACD discs) that I suffer mild disappointment every time I listen to a standard (redbook) CD.
