Your setup sounds good for the most part. I don't like the whole light over the tub though.
You should get ready to buy her a 4'x2'x2' cage though. That should last a couple years, maybe. And she'll have plenty of room for a while. Give her plenty of stuff to climb on too.
my bday is the 20th, bday money is being saved for snake supplies cuz my carpets are going to be big enough soon to need cages of their own
