I am so sorry to hear about Booboo.
I don't have any suggestions on the transport side, but I was thinking about getting her to the vet. Do you have a vet around that would come to your house? For routine things once she becomes immobile, and when her time comes to cross the bridge (which will hopefully be SEVERAL months away).
I just noticed Angels3 posted this suggestion too.

I hope everything goes smoothly for you and her. I will keep both of you in my thoughts.
