Can Apple replace the plastic case on my iPhone 5c?

It's a little beat because I take it with me everywhere and skating. I'm wondering if they can replace the plastic chasis on my 5C its a white one but has a ton of scratches and some dents or chips on the edge. And do you think it'll cost a lot?! Or will they say buy a new one? My screen isn't cracked or scratched either just plastic part is terrible.

If I restore my iPhone will it turn off Find My iPhone?

I had to put in an insurance claim because I shattered my phone and they require you to turn off Find My iPhone. I can't do it in iCloud because my account isn't verified and the email to my itunes is so old I can't even get into it anymore. If I restore my phone to factory settings will it turn it off? Or how else can I turn it off?

Do widgets use any data on my iPhone 6?

With the new update (iOS8) you can now edit your drop down notifications bar on the top with different apps like weather. I was wondering if that would effect my data usage with the weather running as a widget just like if I would open the app?
