Get my apps from iOS 8 onto iOS 9?

I'm not a tech savvy iPhone person, but I'm for computers. But I do have a question. I want to update to ios9 but don't have the space. So I want to format my phone, download iOS 9, and get my apps/data from my iCloud account. Can I do that?

You could delete social networking/messaging app (FaceBook, Skype, etc.) to make space and then reinstall them after the download, this way you won't lose any data. Alternatively, you could sync your phone to ITunes on a computer where it'll store apps and their data and then re-sync it afterwards (and reinstall the apps form your computer) and everything should be okay.

You can reset the device and restore from a backup, and you should get all your apps back.

I go to iTunes and do what it says but I can't seem to get anything on iTunes but their STORE and the syncing part. I remember there being a page exclusively for all of this. I don't want the store? And when I plug my iPhone in, iTunes used to pop up automatically and now I have to do it manually. That's not a problem. Just sayin.
