If you remove that vapor barrier that's glued to the batts you damage the batt as well vapor barrier should be secured if op staples this vapor barrier then they do not need a poly vapor barrier as well again I still suggest that local coding is checked but manufacturer says to secure the vapor barrier that is on the batt not to be just removed or else the r13 value that is up is no longer r13

Yes the paper should be stapled to the wood should have a an overlap on one side also might want to try to fix the compression in yours bats so get your actual r value

Yeah should be flush with the beams and tacked for a complete seal

That paper backing is actually a vapor barrier (worked for an insulation company in the northwest) but I would suggest looking into coding for a basement for higher humidity areas

Yeah I know foam board is normally recommended but in some cases I have seen Kraft batts used in basements depending on the ability to keep moisture and humidity under control
