I have a nearly identical setup to what you're proposing, and I love it. I have the T3 - which is the perfect size for my adult female BP - along with all of the accessories you are planning to get (minus the stand). I would suggest getting the Herpstat 2 instead of two of the VE thermostats, I believe that will be cheaper (and yes, you do need to have a separate thermostat setting for the flexwatt and the RHP). I have the same 40 watt RHP panel installed as well - I was unsure what size to get and emailed Reptile Basics about it, and they suggested the 40 watt RHP for use in the T3. There's plenty of space in the cage for it. As for hides, I strongly recommend the Reptile Basics hides. Also, maybe look into getting a pair of hemostats for feeding and the F10SC veterinary disinfectant for cleaning the cage (Reptile Basics sells these as well).
