They should shed all in one piece all at one time and it looks like she's less than a week away from doing so. The only reason I bring this up is because you mentioned "even the parts of her that have shed seem a little faded". Keep the humidity up (60-70%) and hopefully for the both of you a good, full body, shed will happen soon. If you have trouble keeping humidity up in her enclosure, just mist her directly once or twice a day to help her out in the mean time.

If I were you, I'd also hold off on handling her until after she sheds. I know mine tend to be pretty irritable (read: stressed) during this time, so I try to leave them be as best as I can until after they have their new skin.

If you haven't seen it already, here's a great article that covers the shedding process in amazing detail: http://ball-pythons.net/forums/showt...edding-Process

Good luck to you both!
