Looking for the proper way to attach a basement wall to the floor joist. Is it ok to shoot nails into the bottom of the joist? I wouldn't think so.

You you can nail into them, will you be insulation too?
Not planning on insulating between floors. For the walls I am planning to glue 2" pink board to the foundation. Build the walls with 2x4s 24o.c. then unfaced batt or wool rock. Then drywall.

Start with a wider top plate that touches the sill plate on top of the concrete.
Fire stop between the wall and the floor system is required. We can use drywall, 1/2 plywood or OSB, but there might be local requirement.
We often just use a 2x4 or 2x6 between the top plate and the sill plate.
Level down to the floors and the perimeter of the basement is lined out and is just as square as the house upstairs.
If you do that top plate work first and then the foam you have saved some work later.
Don't forget sill gasket at the floor or anywhere wood touches concrete.
