For equipment, you can go bare-bones with just a bamboo sushi mat. I like to have a few so several people can use them at once. Or go a little more deluxe and buy a kit. Here's one with a sushi oke and paddle, the proper tools for making sushi rice. I'm not a fan of plastic wrap in general, but a little goes a long way here to wrap your bamboo mat. (And you'll be saving a lot of plastic by avoiding takeout containers, just sayin.)
