My response is somewhat based on ignorance, so please bear with me.
With respect to the dailies, whether they are "must do" depends on whether you can val cap without doing them. If you can, they are not "must do"; if you can't they are. I don't know because I honestly haven't looked. I'm doing them strictly for rep at this point, and prioritizing them based on what I want to get when.
You need to grind out the rep with the factions just to spend the Valor you've earned. That puts it squarely into the "must do" category.
