Need some clearing up

[Bartman]

Alright, im going to ask some questions now about my kenyan sand boa. And please dont give me responses that i didnt do research or all that crap, because im telling you i did, for a month, to get all the info i thought i needed to care for these propetly. Problem is that after posting some pics and showing some thigns im starting to get the impression i have things wrong.

Right now i just need to know exactly everything in your guys enclosures.
More specifically i need to know
-what substrate you use
-what depth the substrate should be
-what should an 8 inch kenyan be housed in
-how should it be heated
-whats the best way to get it to eat and how would i go about doing it
-hes in shed now, what should i do to make it easier for him..make a humid hide or something?

what i have done now is
-sand
-now 2 inches
-10 gallon glass tank
-over head heat with a 50 watt white bulb on a 12 hour timer
-so far im not really expecting it to eat but ive tried live the day after i got him and an f/t about a week after..so two days ago. no success

thank you very much, and again..please to comments on how i should know more before buying...i truely never impulse buy and this wasnt one at all, but caresheets are very wrong..even though most were very similar. Im just getting the feeling that their really really wrong.

any info is great!

edit: Im also using 2 pieces of cork bark over the sand on each side as hides if the snake wants with a grass decor in the middle. Shallow water dish with the rim at the level of the sand. Ive seen him drink himself so he knows where it is.

also hes been unburrowed for yesterday and today...is it because hes in shed or is it not warm enough..im using a 75 w bulb and getting 98* above the sand. Hes staying on the warm side on top of the cork bark that is under the heat lamp.
