Screw holes and gouges

Q: I have a 1948 river cottage with beautiful pine floors. When I purchased the property the kitchen had two vinyl tile floors, one on top of the other, which I removed and covered with 1/2 inch plywood then a sheet of vinyl.The property became a rental for about 3 years. Now, I want to remove the sheet of vinyl and plywood and refinish the kitchen floor.

My concern is that I used 1-1/2 inch fine thread sheet rock screws to hold the plywood down and that when I go to refinish the floors I will have 100 small screw holes throughout. I also chunked the floor up pretty bad in some places when removing the old vinyl tile floor, It was held down with the old black tar like adhesive. Is there anything I can do to hide the 60-100 screw holes? How about the chunking I did with a chisel like tools? Maybe I could take pine boards from under the kitchen cabinets?
