Thats a good start. If the containter is very large, I would want to consider adding some plastic plants that you can get for cheap at a craft store to make the young bp feel more secure. Even though its a rubbermaid and pretty cozy and private, the space may still freak the baby out a little. So other than providing some cover on the floor of the tank, your setup sounds good. The DIY rubbermaid setup on here is awesome. You'll need to drill some air holes too if you haven't already or forgot to mention it.

As far as the clay pot idea goes........i'm not sure at all.

And the PVC jungle gym....combine that with the fake vines and leaves I just mentioned, and you should have a very happy baby bp.
