Plastic is down but needs to be tidied up.
Will be difficult to add vents to the other side as it is about at grade.
Pretty good separation between crawl and conditioned spaces
Yes, need to insulate the plumbing.
Thanks for the recommendation for the R30. This is a small job so cost is not really an issue.
Confirming that they should be unfaced due to it being vented? Or is there another reason to use unfaced?

Unfaced because of moisture concerns. Faced insulation acts a a vapor barrier and generally faces the warm side. Unfaced will let the moisture that does get through even after you go through the effort of sealing up the cracks migrate from hot to cold. Otherwise you can run into mold issues. Even if you get faced insulation and put the face up next to the floor, any moisture that gets through is now trapped between the floor and the insulation.
