What all do I need to be ready for an 8 week old kitten?

Okay so in about 5 weeks I will be getting an 8 week old kitten from my best friend. Its been a long time since I have had a kitten, and I am just double checking to see if I am going to be getting everything I need. Im not going to go to the pet supply store for a while, so I still have some time. Ive been looking online every once and a while to see if I have forgotten anything that I need on my list. Now I already have 4 adult cats. On my list I have 2 bowls for food and water, I can use our other cat food plates for the wet cat food. dry cat food, wet cat food, clay kitty litter, a smaller litter box, because we have 4 main coons, and they use a bigger litter box. I also have toys obviously. We dont put collars on our cats, because it messes up the fur on the back of their necks (we used to show them, and it was bad to have a collar on them) we already have a pet carrier so I dont need to worry about that... I seriously feel like Im fogetting something, but maybe its just me being paranoid.. LOL
