I would just stop doing anything. Lightly sand the poly as it peels off and live with it as it is.

Our 'entryway' is our enclosed porch. The floor is wood. I just refinished it last summer and by this, it's already showing signs of wear by the outside front door. My sister has slate in the small area by her front door--it looks nice and really saves the floor. A bakery I used to work with installed a really good, heavy-duty wood floor in the store. It was supposed to last them for 'forever'. within months it was virtually ruined by the traffic coming and going. There's no way, if I had the choice, I'd have wood by a well-used door. Unfortunately, given the configuration of our porch floor, we can't put in anything that adds even a fraction of an inch in height, so tile, carpeting, even a throw rug are out.

I don't mind the table and mirror and can't really think of anything besides art that would fit on that wall. Can't see the table details well but could it be painted? How about red to match your lovely door? What would say "fresh and cozy" to you for that space? Have you thought of a new light fixture? A runner and a larger rug in the entrance could look good. I don't find the clock visible from the door to be welcoming so I'd be tempted to remove it.

Hard to say without seeing how the house is decorated and what other light fixtures you have in adjoining rooms and in the rest of the home.
