Creatine is a waste in my opinion. Unless you care to do endless cycling and just have the water based mass, you're probably better off just avoiding it. It can help, but it's not dramatically noticeable in my experience and a good diet and workout regime can you just as far for less money. Use the money to grab a subscription to Men's Health instead, which despite having a miserable subscription service, has great advice month after month on what to eat, what and how to work out depending on your goals, and so on.
Your body needs protein for a number of things, and whey protein is the most effective as rebuilding muscle. That said, you shouldn't take more than 0.5-1.0 grams of protein per pound (according to Men's Health). If you're looking to tone and build, and not become a total meathead, I'd recommend following that advice. Besides, even eating 1g per pound is a ridiculous amount; I weigh around 180, and I'd be lucky enough to get close that amount, despite regularly eating protein laden meals every 2-3 hours.
