Everything sounds just about right to me. I've found that Ball Pythons (mine, at least) do not like to feed, move around too much, or be handled at all before a shed. From what I understand, the skin feels really tight, almost like a bad sunburn, before a shed, so you can imagine how uncomfortable it might be for her to really be doing anything.

In the future, make sure to raise the humidity in the tank to allow for a comfortable, complete shed. As soon as I notice my BP's eyes turning (they'll become very blue and cloudy) a couple of days before a shed, I'll soak her once a day in a warm bath until her eyes are back to normal, and I'll also spray her tank down with some water.

And I also suggest feeding your BP only once she has gotten rid of her last meal, if you know what I mean. I know that mine shows absolutely no interest in food until she has gone number two, even if it takes her well over a couple of weeks to a month to do so, then she's out and about and all over the tank, ready to hunt. So. Good luck.
