I feel like the tagging for the building itself should be different, as some map compilers will show this as a current station even though it is completely disconnected from the mainline.

Thank you for correcting my mistake, I believe iD did this on its own

buildings that were deleted are simply just tarps for shade from sun

Short Pump and Tuchkahoe are just census-designated places and do not have their own governments. Tuckahoe is a magisterial district of Henrico County but it has no individual government. While I understand it appears to be a loop, on the southside of the James river, there are interchanges with VA 150. Once VA 150 ends and becomes VA 37, it no longer has these interchanges as it going through neighborhoods. Looking at streetview level images of the two roads can clearly show why Parham should be primary and Chippenham is a trunk/motorway. As a local of the area, I know this for a fact. Looking at the trunk roads in the RVA area, they all appear to have been upgraded to trunk roads by yourself.

Well looking at the Highway classification wiki page, for state routes like Parham Rd (VA 37), "highway=trunk is for highly important routes that connect large towns and cities" Here, there are no towns or cities being connected by this road. This road also does not fit the traditional definition of a trunk road. Either side of the road can be seen to have private driveways to private homes. It seems much more appropriate to classify it as a primary road.

Why did you retag this road as a trunk road? This road should be classified as primary.
