I have a low opinion of Carlolinal BS, but that is just me. I couldn't get your links to work either.
I work with New England Herpetoculture for plants and viv supplies, inc lights (I like Jungle Dawn with Exo-Terra hoods). Josh's Frogs is a good source too. Both very informative, although they are not specifically geared to snakes. Universal Rocks supplies beautiful backgrounds taken from real rock faces.
You might benefit from two books:
Philippe de Vosjoli The Art of Raising Snakes
Philip Purser Natural Terrariums
Both are focused on naturalistic display vivs. Both are a bit dated, but the techniques/tools/materials for this hobby get better all the time. You also need a GOOD care book on the animal you choose. If that animal is primarily nocturnal, you may never see it during classroom hours. My Desert King never shows up during daylight, and he burrows. I'd have to uproot all the plants if I wanted to dig him out during the day. I leave him be.
Do you have a budget? An 36" Exo-Terra can be $200-300. A fish tank is doable, but a pain with the hood and lights on top. No way to lock it either (at some point, some unauthorized person will want to get in there). All told, I several hundred dollars on the corn snake's set-up. It is not a cheap hobby.
