If you have the original equipment wipers, the refills are the way to go. IF they've ever been replaced by anything else, including the "Toyota" branded Sightline wipers most dealer parts departments carry, you may need the full wiper. I used this sale to stock up on refills. so much better than anything else available aftermarket on the 200.
When I do brakes and rotors, I always like to have a set of hardware on hand. On the front, the pins can corrode or get stuck, and on the rear, the clips that the pads slide in can usually stand to be refreshed. You also don't want to have to stop mid-job because of a torn slider boot on the rear. Even if you don't use them this time, you probably will eventually. I also always keep a tub of caliper slide grease handy, but that's from a regular auto parts store.
