I had to look back and see pics of Petra when she was 8 months to remeber that she was insane as well. This is a picture of her on my ankle/foot (I was laying down). As far as tameness...that was the extent that she would hang out, for like 2 mins and walk away/run.
He will chill out, and I suggest that you keep taking him out and enjoy his crazyness because you'll miss it when he's bigger, smarter, and is pushing your pillows out from under you, while you are trying to relax.
Also I utilized the bathtub/sink and gave her lots of chill soaks like 3-5 times a week. When I go into my herp-room now she jumps on her cage door, crawls out and walks to the bathroom/tub across from her room. She equates me with food/ soaking in hot water which she LOVES (and i equate this with "she loves me!" lol)
It's definately true about them loving the ground, seems Petra freaks out when we are going down stairs, but I have a fear of heights so I can understand. 
Where did my baby cyclura go.....?
