Welcome to the forum.
If you are going to use a tank then you probably will want to use eco earth to keep the humidity up.
Now my ultimate question to help with all your questions:
Where are you located??
I am sure we have a member or couple in your area that may be willing to you out, plus it would give us an idea of what breeders you might have close by.
I'm in Malden Massachusetts and I was gonna use repti bark I heard Eco earth holds to much water and may cause scale rot
