New iTunes- how do I find my Devices?

I just got an iPhone 4, and I'm trying to sync the music from my iPad onto it… I broke my laptop this weekend, so I just installed iTunes onto my PC desktop. So far, I don't know what to do, mainly because the latest version of iTunes is super confusing and I can't find my "devices" on there… Someone pwease help?

Added (1). I've already connected both my phone and iPad via USB cable and nooothing is showing up

How about connecting it with a cable to the computer? If you haven't unselected the automatic sync it should do the job itself.

But yeah, the device isn't anywhere. It appears once its connected to itunes, either by the cable or wi-fi. It will be right next to the itunes store button to the top right.
