I use my card's resampling (X-Fi) normally. Game mode works well for general usage so I don't change things around, and I not notice any degradation. When I'm doing pro work I switch it to audio creation mode and disengage resampling.

The DAC does not upsample the PCM stream. The audio card's drivers (or Windows KMixer) do that, and do a pretty poor job according to most. Alternative software resampling, such as SRC, will do a better job.
I have the digital output of my Audigy2ZS looped back into my 0404. The A2ZS only has 2 options as far as sample rate output, 48 or 96, so I picked 96. On the 0404 I have to have it at 96 also just so that everything works together. In foobar I resample to 96 which then goes right to the 0404.

This statement it technically correct. However, with a proper setting of the software one could get a bit-perfect PCM to be fed to the DAC. There (rougly speaking) a reciever chip "refreshes" the data (buffer, reclock, filling missing samples etc.) and feeds the DAC chip. The DAC than does the real/proper/needed upsampling to the MHz range to do it's job right.
I played a while ago with our HP spectrum analyzer, feeding "properly" 2x resampled (48->96) sin waves PCM to Wolfson's DAC on AV-710 just to see the output. It might sound better, but looks worse (I'm not an expert, don't ask me why). Could be the resampler,
If it sounds better to you, sure go ahead...or try a different analog stage.
