The nuts on the the filter are the counters. You apply resistance to these in a clockwise direction; then loosen the outer one counter-clockwise. There's one on each side. The one on the passenger side is larger and looks more like a nut that you can put a large open-end wrench on. The one on the other side with the L-shaped hose end is a smaller nut in terms of thickness. If you do not use the counter nut, you'll destroy the hose attached at that side.

Your plan looks pretty good to me.
