I had always thought he was found within the Pyramids of Giza but just recently heard he was actually buried in Luxor which is considerably south of Giza (I think). Are there pyramids in Luxor as well, or did his tomb have nothing to do with pyramids? Or am I completely off the mark? If the latter, please give me a quick rundown of the geography as well because all of these places and landmarks are swirling around my head right now. Thanks!
Tutankhamun had nothing to do with the pyramids. The Pyramids at Giza were built for Khufu (~2560 BCE), Khafre (~2570 BCE), and Menkaure (~2510 BCE), all during the Old Kingdom of Egypt. Tutankhamun lived during the New Kingdom, and died roughly 1323 BCE. So, as you can see from the dates, there is a major time difference between the pyramids and Tutankhamun.
Here's a map of Egypt, with Giza (the Pyramids) and the Valley of the Kings on it.
The reason that Tutankhamun's tomb is so interesting has nothing to do with the grandeur of it, and everything to do with the fact that it was found intact. Every tomb we found prior to Tutankhamun had been looted in antiquity, including the pyramids. It is getting a lot of attention right now because it is possible that the tomb was also the burial place of Nefertiti, the Great Wife of Tutankhamun's father, Amunhotep IV (Akenaten).
