I am thinking do I move her last but seeing all the stuff going out might really terrify her
do I move her first and maybe keep her in the bathroom at the new place and close the door?

I don't have any real suggestions as I've never moved a pet from one home to another or had an extremely timid cat. However, I am sure there are others here who have and will have suggestions.

I would like to say that IF at first you put her in the bathroom at the new place and close the door, someone .. don't know who... might just open the door and out she goes. Be careful with her. Good Luck with the move.
