I would leave him completely alone for one week starting from the day you got him.
After one week, offer a live hopper if you can get one, or you can try a f/t. If he doesn't eat the f/t, try a live hopper the following week. Your main goal is to get the animal eating. Once he is eating consistently then you can worry about switching to f/t.
I feed all my snakes in their home enclosures. Moving them to another enclosure is just making the situation more stressful. There is really no reason to move them to another enclosure.
PS: you went to the wheaton show? I was about to go but then I had to move out of my apartment...haha. Perhaps I will see you at the next one?
