It will be coming out in late summers or a autumn (pardon the spelling).....
It will not ruin the story cause it will be a continue from the anime just that it will be better quality than usual plus more action
Last of all the reason of the movie is cause the story around the Uchiha bloodline is big and many people want to see Itachi (who the movie is about mainly as ive gotten information about) and the creators of Naruto decided to make a movie of it all
The raw of the movie wont be so hard to get cause it will be aired on Japanese Television or in worst case in theater which we would have to have a week more to obtain.
Hope that answered all your questions
