Anime is canon as far as I know, some fillers fit into manga story, It is his work I believe. And about numbering, we numbered episode because of Naruto Shippuden (part II) was introduced in anime, thus not continuing from Naruto (part I), the chapters do not exactly cover the length of video in anime so episode numbering differs from manga chapters.
