One good thing to go ahead and do is zip-tie any extra doors that you don't have a need to open. Most large cages have a huge amount of doors and a lot of them aren't needed.
I'm glad that everything worked out for the best and Kiwi is okay. You were very lucky that nothing happened to her, not only when she was running around your room but also when she crawled into your pocket. Yes, it's very sweet she came to you and saw you as being a comfort zone, as it shows she is bonded to you, but if you had simply rolled over in your sleep, she would have been crushed, and this would not have turned out so well.
