Under the shoe, possibly a tailors ham (even though mine is shapped more like a ham). Or, being nothing is true to size, possibly a cylinder to store needles.
The doll, maybe a weight, or just something that was just made. It will all come together once completed I'm sure. It is a very nice pattern.
I was just thinking, maybe that thing under the shoe, might be some kind of stuffed roll used when pressing sleeves.
Some other stitcher on this site might be able to come up with some other ideas.
