Welcome to BPNet Edie. It's wonderful to see pet owners/hobbyists that use forums this way.Since you're already aware of the benefits of keeping your T's in rubbermaid, you've likely already read here that a lot of us keep our bp's in Rubbermaid, Sterlite or Iris brand tubs....it's a great way to set up a BP, especially a nervous baby and very cost effective for you. There's a ton of threads about setting up tubs for babies but if you need any help, just ask.
Best single piece of advice I was given when it comes to new snakes...set them up and leave them be for a week...no handling, no attempts to feed, just basic cage maintenance. It's one of the hardest things to do but it does allow these naturally shy snakes to settle in at their own pace and starts things off on the right foot.
