Just bought a green anole gecko.. help!! how do i keep.........?

Hello(: i got a female anole yesterday at petco. right now it has a UVA/UVB lamp and heat lamp(60wts) above the 10 gal tank. Im feeding it mealworms because that is what was being used at petco but she wont eat them. they are in a little dish in the corner of the tank. is something wrong?the tank has a stump looking display i bought at walmart that has plastic plants protruding. also, how do i keep the humidity level in the tank? i am using a $1 spray bottle i bought at walmart and put purified water in. I spray the tank like every hour but i feel like there is a better way or maybe i am spraying it too much? also, would it be appropriate for me to hold the anole or not? she is approx 5-6in from snout to tip of tail, please help! ive never had a reptile! :) thanks!
