What accessories will I need for my Wi-Fi ready Blu Ray player?

Hello! Technologically ignorant here. I just ordered a Samsung BD-C5500C Wi-Fi ready Blu Ray player. I have a Samsung 32in LCD television. I am pretty sure HMDI cables are a given for the picture quality but what about the Wi-Fi? What sort of accessories will I need in order to be able to watch Netflix via the internet the day it arrives? Any help is much obliged :)
