Bearded dragon question...?

Ok I might get a BD soon I'm gonna get some rocks from outside boil them for ten minutes. Would a 40 or 45 gallon be good enough for a bearded dragon? I plan on feeding him crickets and Phoenix worms I was gonna order 250. Crickets online and 100 Phoenix worms. Sound good? Also what kind of UVA and UVB lights do I need and what temp do I need for the aquarium? And how often should I Change the bulbs?
