BTW, I dunno how accurate you want to make this, so feel free to ignore this, but in case you are interested...
I have the strength reports for the 11th Nordland Division from June 1944. They had 10 Stugs, 1 Panzer IV and 5 Panthers that were "ready for action". They also report 94 apcs and scout vehicles. All in all the infantry seems to have been organized as Panzergrenadiers, so that would probably be more correct than the SS Infanterie Units.
In terms of (non-MG) small arms:
Looks like there were no StG44s in the inventory at that time.
