Long nosed leopard lizard breeding?

I have a male/female pair of long nosed leopard lizards that I'm pretty sure have just reached sexual maturity. The male has become quite aggressive to the point where I had to remove a cage-mate for safety. I noticed that he is also excreting a waxy substance from his femoral pores as well. The female hasn't changed her coloring yet but if she should I'm wondering where they lay their eggs. I do not want her to get egg bound, so I'm wondering if I should put a breeder box in with a different bedding, etc. All the sites i have visited talk about how many and the frequency of eggs but they have not mentioned where they are laid. Also, if you happen to know, is it better to remove the eggs for artificial incubation because they are known to eat smaller lizards given the opportunity? and if so what temperature is best for incubation.
