That it is, not everything is easy to find even if searched for.
She will be tired from the strain/remarkable effort of laying her ooth, and she will be quite hungry. Feed her as much as she wants today, and it will help her return to normal soon (at least until she starts on her next ooth).
The agitation was most probably her preparing for the final event, as they prefer to be left alone the day of two especially leading up to the laying process. Also some females can be rather protective of their laid ooths, so it could have been her motherly instincts already as well.
Her falling though is a concern, even more so when she is gravid (pregnant) as she can be injured much easier during that time due to her enlarged abdomen. I would suggest changing or adding material on her lid to offer her better grip. For example plastic/fiberglass mesh typically works great, but some can require a bit more and the "rubber" shelf/drawer liner material is the best.
