Yes to the basking light. No to the egg laying bin. I plan to go to the store tomorrow for something she can lay eggs in when she is ready. I'm guessing I'll just leave it in there at all times. I've read to mix organic soil and play sand. Is that correct?She looks much better in these photos!!! From the last set I was worried because it looked like she was way over heated in the top left pic. I'm guessing you made all the adjustments?
