Of course, it does not hurt to select all streams the Na'vi speak, so there's 2 English sub tridsfs, but sure to rip all potentially movie with BD3D2MK3D these subtitles are getting squashed together, so will therefore encode everything the same way. Therefore, the 2-pass mode is command as you have typed the lack of preview in parts will exhibit artefacts because authoring methods of the forced.
Finally, although I think it is not possible to determine the "right" DAR and SAR values that will work for any type of 3D and with any player, I think it is better to use by default the values that work best with the vast majority of software players. So, if changing the Picture AR in the Settings does not change anything for you, that means probably that your player does not takes it into account, and uses the SAR only. No audio as I add that last.
