Do a water change to get the NO2 under 5 ppm, and keep feeding the bacteria with ammonia. Looks like you are almost there.
When the bacteria can remove all the ammonia (up to 3 ppm) in 24 hours, and no NO2 shows, it is done.
If you will be stocking right away do a couple of massive water changes (2 x 90%) to get the NO3 way down.
If you will not be stocking right away it does not matter about the water changes. Keep on feeding the bacteria. Do the water changes right before you are ready to stock the tank.
It is also OK to remove all the water if you still have to plant or rearrange the hardscape. Just fill it back up with dechlorinated water. Feed the bacteria or not, depending on how soon you will be stocking the tank. A day or so without ammonia won't be a problem. Longer than that, I would add ammonia.
