With him being that small glass is fine, its better. It keeps in heat and humidity, take out the heat bulb asap. It only needs to be around 76-79. No soil just paper towels. And he/she sounds about 3 weeks old.
I hate the repti fogger ive seen them not work right out the box. I use a cool mist humidifier with a hose. Try a cone cool mist humidifier for like 40 and get some hose and a cuplet. :) works wonders. Also veileds dont need a constant high humidity, 60% most the time is great. Too much like 80%...
The first day of any of my chams, i let my dog and cat smell them so they dont get curious, they never come in my room because the doors shut anyway. But both of my furry friends are shy anyway. One time My oustie was on my bed and my dog jumped up and rex flarred up and hissed so she ran away...
Just a preview of his color. Breeder i got him from said he showed the most color he'd ever seen on an oustie, purple, orange, yellow, red, green, blue.
