How to sync everything to a new iPhone?

Okay so. I have an Ipad mini and iPod touch. I'm getting an iPhone 5s this christmas. On my iPod touch I have music I got from a website, how can I put them on my iPad and iphone? And contacts? My laptop recently crashed so I couldn't look at itunes and stuff. When I get the iphone do I need to sync that with the computer? But its broken? Can I put it on a new computer? I don't think I can so what will I do? How do I back up my computer like itunes? Thank!

Ok, so you can't use your laptop…

1. Get another computer, download iTunes on that, sign in to your Apple ID.
2. If your content is all there, skip to step 4.
3. If your content isn't there, connect your older device to sync with your iTunes account, it should automatically upload all of your content.
4. Connect your new device to your iTunes, sync all of the content.

Finished, if you need any more help, contact Apple, or go to a tech forum.
