The ground vapor barrier and the vapor barrier installed between the subfloor and flooring are adequate.
You don't want to put another vapor barrier on the underside of the floor joists. If the old insulation is bad from moisture, etc., you can replace it between the joists.
Don't crush the insulation batts. That defeats the purpose of the insulation.
Good Luck!
