I have a Maine Coon. You're going to need one of those metal combs for grooming. If not they can get matted up. Same goes for any long-haired cat.
When you bring the cat home, have its litter box, food and water already set up. Give him/her a few minutes to explore, then show the cat where they are. The litter box should be in an area that is quiet and out of the way. Cats don't like to be disturbed when in the box. Keep the litter the same as what they are used to. Sudden changes can cause big problems. Food and water should not be near the litter area. It would be kind of like eating your dinner in the bathroom. I advise most people to keep kittens in a safe room like a spare bedroom until they are big enough to jump from whatever surfaces there are in your home. Kittens have no fear and think nothing of jumping off of a countertop. They can injure themselves very seriously. We kept ours in the room when we were at work or asleep. If you're home, they can have the run of the place.
Electrical cords, houseplants, paperclips, staples, rubberbands, all sorts of things can be a hazard to a cat. Go through and cat-proof your home.
Cat trees are great for scratching and climbing, you'll at least need a tall scratching post. When you give a cat the proper things to scratch on, they won't go for your furniture.
Get the kitten spayed or neutered no later than 5 or 6 months of age. Many behavioral issues can start if you don't.
