Case 1: I have an iphone which has all of my songs on it but recently my hard drive crashed and i got a new computer. i still have all of the music on my iphone, and have bought new music on my computer. I want to transfer my music to my iphone without losing everything on my phone, and transfer back anything on my phone onto my computer (including contacts, photots, etc.). How can i do that?

Case 2: For christmas i got a brand new laptop!!! I downloaded itunes, and all my music erased by accident, but i got them back. I kinda downloaded the movies online, and put them on my phone. How do i transfer all my movies to itunes?
