The next step is to patch all of the holes. Make sure you have driven all the screws below the surface of the wood. If you havent, do so before continuing. If you are having trouble getting one below, reverse it out a bit, then re-sink it full throttle. It that fails, just accept that it was not meant to be. I have a few screws that stubbornly remained above the surface but they aren't too noticeable once you have painted. I guarantee no visitor will notice (nor point out) any imperfections they see. It's all about the game.
Patch all the holes and let it sit overnight. Zzzzzzz...
When you are done with your celebratory beer, wipe the whole cabinet off very good with tack cloths. Don't be stingy. I went through six wiping it all down.
[Update- I used clean, cotton shop cloths to wipe of the cabinets well, then used one tack cloth to finish it all off. Worked much better.]
