Welcome Courtney.
Sherry gave some good advice. A cat tree is definitely a bengal's best friend. A wand toy like da'bird, neko flies, or flying frenzy will probably be a favorite activity when you play with him, and is a really good bonding activity.
Normal behavior initially is often fear and home sickness, but kittens usually adapt pretty quickly (a matter of days). Initial gotchas? Make sure to take things at the pace he's comfortable with. Don't force yourself on him, you're not a comfort to him until he decides differently :) Kitten colds are pretty common, and you have to take those seriously. A runny nose or runny eyes, or sneezes requires a trip to the vet. It's also pretty common for a kitten to have some parasites, which sometimes take weeks or months to manifest themselves as runny, smelly poo. So if you run into that, there's lots of reading here on the forum, and people who have gone through that.
Food and litter? With all the other changes in his life, it's best to keep those consistent for awhile, using what he was using at the breeder's place if possible. Then you can switch to what you want to use once he's settled. For nutrition, your kitten will need to eat 5 or 6 small meals a day for the first couple of months, and you should let him eat "as much as he wants" for the first 6-12 months or so. There's a lot of really good resources for nutrition. My favorites are:
http://www.littlebigcat.com/ and the book "what cats should eat" by the same author
http://www.bengalsillustrated.com/ a really good print magazine about bengals with all kinds of great info (including nutrition)
http://www.catwatchnewsletter.com/ - this is also really awesome general info about cats, from Cornell University
When it comes to food though, one thing to always remember is that when you are figuring out what his diet is going to be, he gets a vote! (or maybe more accurately a veto). It really doesn't pay to get stubborn and try to insist on him eating something he doesn't have a lot of enthusiasm for. So it often ends up being a compromise between something you think is nutritious and something he thinks tastes great.
