How to move all of my stuff from a shared iTunes?

So my parents got me a Macbook Pro for my graduation back in June, and I want to move all my stuff from the family computer to my laptop easily so I can move my iPhone 5 to my laptop instead of having it connected to the family computer's iTunes. As far as I know I can't move purchased items like apps or videos, but I can move songs. I was just wondering does anyone have a simple method for a smooth transition with the stuff from the main computer to my laptop and my iPhone being synced with the main computer? If so it would be greatly appreciated. I've been holding this off since June when I got the computer and I haven't really had the patience to mess with the iTunes since I got my laptop, and I don't want to update my laptop so I get the new version of iTunes which I don't want. So if I could avoid doing that along with the transferring, that would be ideal. It's not a big deal if I do have to update it, but I'd just rather not.
