You need to expand your upper arch. The outside edge of your lower molars should touch the middle of your uppers.
I see the nose thing, but even more important than that is chin projection, so sliding genioplasty for sure.
IDK about maxillary advancement. I'm not seeing it. Possible impaction needed though.
Your first step should be to consult with an orthodontist and get some x-rays taken. During that consultation, insist on a referral to a good max-facs surgeon.
