If you do insist on grinding take it off the bottom. Looking at the wear pattern you showed you need to let the shoes seat and then you will have room. Back in the days of manually adjusted shoes we set them for just a touch of drag to get them seated. Disc brakes drag all the time. Keep in mind that when you do use the brakes, it takes some time for the heat at the drum-shoe interface to travel to the outside.
If the wheels turn free after releasing the handbrake you are probably good to go.
As for the handbrake pushing the brakes out even with the pedal down, yes that is normal especially on new shoes. Pressure to the rear brakes is regulated. With the van raised in the rear the regulator kicks even even further as it thinks the van is nose diving. It works both on inertia and angle. Using the handbrake will push the shoes out and with them not seated that will wedge,, distort the drum, etc and move out letting the brake pedal sink a bit more. I just did a van with the GoWesty HD drums and it is amazing how different the handbrake and service brakes work. Now installing the front big brake kit on that van.

Granted this is from 2011, parts design can change, but on the samba forum, found this comment:
"Speaking to a VW mechanic yesterday, he mentioned that he has seen a lot of similar problems with aftermarket brake shoes being out of spec
- the metal plate is too long, so which causes the shoes to drag no matter how loose the adjuster is set, and to solve this problem it is usually necessary to grind off some of the metal at one or both ends of the plate."
NOT saying this is the issue but I will measure my new shoes at points where they fit into slots at wheel cylinder pistons and lower pins, against 2 older used sets of shoes. Both sets of used shoes appear to be from different makers.
