Do go slow, just one step at a time & try to go at her pace, once she seems fairly comfortable with something move on a little more, she may not want to interact at first when you take her in the bath as it's all new but keep at it & keep sessions fairly short to begin with, put some toys in there for her too if you can.
She doesn't need light during the day, she should be sleeping for most of the day, keep the lights fairly dim or at least not too bright in the evenings when you have her out.
