ITunes won't let me add new music onto my iPhone?

I've been trying to add this new playlist, but every time I try to do that, the songs show up on my iPhone on iTunes and it has that 'syncing' circle next to it, but it's paused and not moving (so basically nothing happens).

I manually move my songs onto my phone, it's not jailbroken, there's space for the songs on my phone, and this happens sometimes but usually by the second or third try, it starts working.

I've tried about fifteen times today.u_u

Added (1). Broadway: It won't let me update it either; I've tried restarting my computer but every time I click Download iTunes 10.6 nothing happens -- nothing starts downloading, nothing pops up.

Turning off network on iPhone 4s so it doesn't roam?

I recently bought a 4s a few months ago and I live in Canada and I'm going to the US for a week tomorrow. I was wondering how I can just my network off or whatever it is so I don't roam at all? Cause I want to use my phone for taking pictures and stuff. Also, if I get Wi-Fi will I be able to use mobile network apps like facebook and instagram or will it charge me? I'm thinking it's Wi-Fi so it shouldn't matter. Bottom line I just don't want to be charged at all. I'm on 3G if that matters.
