Yes, I'd prefer the forced subs be auto-selected with the audio track.

Also, I prefer the white text over the yellow for the buttons.

I have no preference either way on the track selection screens.

Another thing - I think it would be OK to lower the bitrate of some of the audio tracks instead of leaving out subtitle options - for example the commentary tracks are prime candidates for using a very low bitrate on them. And maybe we could even slightly lower the bitrate of some of the dub tracks.
Worst case scenario, I could also encode the video with a slightly lower bitrate - the difference should be absolutely minimal.

Thanks for doing this guys - I'm glad someone stepped up because I don't like this kind of work much.
