Needs a vapor barrier as well. 

This is how they suggested we lay everything out so we will be protected in the event of legal action (My W2 job requires almost constant credit monitoring and can not have any legal issues---lets just say a government job).Also when looking at how everything is set up, take into consideration that everything listed above has been created since 2017 with the exception of the tax office and her being a cosmetologist.

Her being ok with you doing it is a win already and smothering her with too much enthusiasm will make things harder, not easier.
