Interesting. Let's see if I can make the same distinctions with Star Trek: The Motion Picture. 1. "The Narada is wery similar to the death Star in terms of destructive ability." So is V'ger. 2. "Important peACEFULL PLANET blownup...check" Not a planet, but the reaction to the destruction of Epsilon Nine was analogous to this. 3. "Old mentor figure living in exile...check" You mean like how Spock exiled himself to Vulcan to undertake Kohlinar? 4. "Cantina scene, j J wanted one but decided not to go trough with it..Check" I've never heard of this rumor before, so I'm not giving it any credence until some source is named. 5. "Final battle onboard the Death Star/Narada...Check" You mean like how Kirk, Spock, Decker and Ilia entered V'Ger and got it to stop it's attack on Earth? 6. "Hero without purpose on Iowa/Tatooine...Check" You mean like how Spock didn't know what his purpose was until his experience with V'Ger allowed him to find it? I don't think Robert Wise had Star Wars in mind when he made his film, and yet at its core it has the same elements you named, which I'm sure I could find with a ton of other movies too.
