Yes, board up that gap in the peak, if you can't do it from the other side then from the inside is fine provided it is completely sealed to the rest of the leaf with no gaps anywhere.
Regarding your vapour barrier - definitely do not put 2 vapour barriers in a single assembly, that is asking for trouble.
Ideally it would go on the warm side of the cavity insulation...
Do you also have insulation behind that OSB on the ceiling inside the vented cavity? If you do, then I would be tempted to remove that anyway to guarantee there is free air flow behind your roof deck.
