Well first things, the breeder will generally provide you with a small amount of the food that they have the kitten on (kittens are especially snesitive to changes in their diet) You may want to see if you can provide the same food, or even a better quality food like Nutro or Royal Canin. I do know that a lot of bengal owners feed them raw, however, it is a big deal to feed them this way and better off for a more experienced cat owner - If it is something that interests you, there's lots of owners that feed raw and can give you better info on this.
You will need a shallow wide dish for food, possibly slightly elevated (kittens especially, tend to eat too quickly, and then they get upset tummies) your kitten will also need a water bowl, however, I suggest a fountain such as a cat-it (my favorite) fountains encourage kitty to drink more, and I've found that the running water stays colder and fresher.
You will also need to have 2 boxes for litter, I suggest covered, with a litter of your choice. I prefer all natural clumping litters like nature's miracle/ World's Best Cat Litter, however, there are a variety of litters to choose from. It is suggested by the vets though that at the time of neuter you use a natural/ nonclay /nonclumping litter. I suggest staying away from clay litters because they're dusty, and the dust is bad for kitties. (also get a litter scoop, obvoiously)
I would also suggest a couple of large, clean tupperware containers to keep the litter and food in, as well as a litter locker to dispose of your old litter into (Note: there are flushable litters, but they are a bit more expensive in general)
for toys, may I suggest a couple that will be really great for hand-eye (paw-eye?) coordination? they keep my kits absolutely tired! Petmate Looney Loops, Kat Twisties, and Cat Crazies. They're hard plastic and the spin and bounce and roll. Also a Cat Dancer, they're so simple and so fabulous. Do not let kittly play with wand toys or toys with feathers or ribbons by themselves though, they could swallow them and get sick!
Remember until your kitten reaches 6 months old, catnip won't affect him or her
