Getting braces to fix my overbite/overjet, would I still need jaw advancement surgery after I fix my teeth? (photos)

So I'm going to my orthodotist to get braces to fix my teeth, but I think I also have a weak chin/receding lower jaw, correct? Would getting lower jaw advancement surgery after I finish with braces give me a more square jaw, or are braces enough for that? Lastly would a chin lift/neck lipo be something for me as every time I lower my head, my chin disappears? thanks!
