*my snake seems to like to burrow under the bedding on the cold side of the tank away from the heat lamp...could this mean the tank is too hot?
The two main reason I see based on your setup are hides too big (it burrows for additional security, and hot spot too hot (not being regulated with a t-stat.

*as far as creating humidity...would you guys rec'd a spray bottle and misting the bedding a few times daily?
It's one of the option however depending on the bedding it can create molds, the best way to improve is to use a UTH instead of a light, use a bedding that holds humidity) , place the water dish partially over the UTH

*could a snake this young really eat live small mice or should I stick with the frozen arctic mice and heat them up as rec'd by a few of you?
They can take live right out of the egg.

There are a lot of things that need to be addressed husbandry wise for an animal that size.
