Yeah, these lizards are very sweet, usually get quite tame with daily handling. Your male will settle down soon, just keep trying to handle him.
Yes, the girls get very thin after laying, you can offer them the waxies, and they also like superworms, moths, and grasshoppers as well as the crickets.
Since you just got them, I dont know how many times they have layed this season, but usually have another clutch about 3 -4 weeks after the first.
So there appetite will increase again, quite quickly if they are going to lay again.
This may be there last. Do you know their backround? (keep up the calcium) 
Some of my girls are gravid now with their 3d clutch, should be it after this.
What are your collareds names so we know who we are seeing,
