Hello and welcome to the Naruto Brigade, Shuriken Don. If you wanna join let us know, but for now here's thy info:
The Naruto anime consists of 220 episodes, originally aired form October 3, 2002 to February 8, 2007.
The original Naruto anime has also spawned 4 OVA and 3 movies (I think). This means the story of the movies/OVAs take place sometime within the time frame of the original anime.
Now - after the conclusion of Naruto it's a time gap of about 1 year until Naruto Shippuuden picks up the story (this goes for both manga and anime). But yes - you could easily say it continues the story. Shippuuden is currently at 56 released episodes.
