Your cage really isn't good for a dragon, you would be better off going to walmart and getting a large rubbermaid tube for a temporary enclosure. The mesh can't hold heat and as you've figured out, there is no way to safely heat it.
Superworms can't be feed to a small dragon, it will impact it. Use crickets and soft worms like butter and silkies.
It does seem to need more customizing and more work than necassary to make suitable for a bearded dragon. You may want to check your craigslist locally by entering:
Fish Tank
Aquarium
Reptile Enclosure
Fish Tanks
Aquariums
*** ALL 5 OF THESE WILL RESULT IN DIFFERENT SEARCH RESULTS, adding an "s" and making the word plural makes a difference. I get cages and tanks for FREE all of the time. I hope you have just as good of luck!
Yes heat and uvb are my main issue and the basking spot i provided seems to be 90's F and am using a hundred watt bulb and no uvb yet. I set them up today and they are five week old dragons ones a red phase dragon and a citrus color dragon. I have them house together right now for a limit of time cause some reason the company shipped me two dragons? At the moment can i speed growing behavior.
