Shortening a jumpsuit pattern

QQ - I'm working on a jumpsuit pattern that I'm shortening by 2 inches in the bodice and 2 inches in the legs for a friend who is 5'0". When I redraw my pattern lines, do I choose a point 2 inches below where I cut and retaped the pattern to reconnect the line? I am new at resizing.

Also what do I do with the notches and other markings?

thanks!
