Yes, I sanded after I grain filled. The grain filler made the entire cabinet look "muddy", even after wiping down with burlap. I should have taken a photo. However, the sanding did not remove any of the grain filler. The surface is pretty smooth.

I've looked at some videos on YouTube and it looks like you do not sand all the way to the wood again after applying sanding sealer. You just scuff sand it and try and make everything nice and smooth. So tonight my plan is to spray the entire cabinet with a couple of coats of sanding sealer. Tomorrow night I will lightly scuff sand it, and then if time permits I'll begin applying the toning lacquer this weekend.
