Question about progression.

In regard to unlocked gear, or updated hunter notes, how does it work exactly with quest completion? Right now in Bherna for village quests I’m on 3 star low page. But in the hub I’m on HR 2 page. I did a nargacuga capture quest in the hub, and strangely my hunter notes did not note narga, and the armor page shows every piece except for his chest piece which I find odd. I suspect it’s because the corresponding small monster part needing to craft it I haven’t found that monster yet?

I know this post is kinda rambled but, how exactly should I be progressing? Do a page of village quests then go do a page of hub and go back and forth? And how do I know my gear is appropriate for the quest page available as far as sustainability to the damage output?
