I'd take the bark out of the bottom of your viv when you do your first full clean and just have a plain bottom or a few paper towels. When I bought my male Veiled, everything was set up for me at the breeders and he unfortunately put substrate in the vivarium, which, as you can imagine after about a month of being sprayed twice a day and a dripper on for hours at a time, turned to mud. Your viv will be a much cleaner and hygienic environment for your Cham without the bark.
Perhaps also a few more plants or a couple of bendable jungle vines would be good so that she can climb around the entirety of the top half of the vivarium - a good dense area of plants at the back is great for when she just wants to hide away for a while, especially when she's getting established.
Try and offer as much variety in prey as you can - hoppers (juvenile locust) are an excellent feeder and my lad loves them - also small Dubia roaches, calci-worms, Silkworms and curly wing fly are all good to feed. Steer clear of waxworms apart from as a treat, as they are very high in fat.
