To Downsize pot or not to downsize the pot...

[Irielicious]

I have one orchid I have been able to keep alive after moving it from sphagnum moss into bark. She lost all but two roots which were aerial roots. Since then she has put out 8 new roots and one flower spike. Her leaves are much smaller as you can see. I need to repot her as she isn't really in the pot securely. The issue is should I downsize her pot to fit how big she will be with her new tiny leaves?

Her last few leaves from her old growth are paper thin and very dry but they are holding on. Even after all the trauma she still flowered for me. I need her to put out new leaves too as even her newer leaves are limp. My other questions are should I just cut off her flower spike so she can use the energy to put out new leaves? Should I wait to pot her until she's done blooming?
