How to buy a cheap iPhone 6?

So I've been wanting an iPhone for the longest time. The only problem is that I don't know how it works. My mom said she'll buy it(I'm 17), but she doesn't think she can because she needs good credit or something like that. Online it says $0 for the iPhone with the 2 year lease, but how does it work? And will it be expensive? I currently have an android and I'm with Metro PCS. Can somebody explain?

Erase my iphone through Find My iPhone?

I need to restore my iPhone 5 since I was locked out due to my forgetting of my pass code, and the only way to do this is to erase through Find My iPhone. However, it says that I will not be able to track my phone after doing so. If I erase my phone and then reinstall Find My iPhone on it, will I be able to track it anyways? Also, after erasing it, if I sync it to my computer (which I believe I've done before) will I be able to get some apps, photos, music, etc. Back?

People staring always at me help honest please?

People is staring at me. In class today a girl laughted and she looked at me and i looked back we were holding eye contact for like 1 second then i was turning away. And in class she was laughing with a group and i wasn't sure if they laughing about me or they just laughing at something else i was the whole lesson just glancing and thinking of the possibilites that they are laughing at me. And in public people are always looking/staring/glances at me. I'm not paranoid becuse i've seen it with my own eyes. I've quite small for a man i'm like 5,6,5,5 not quite sure i'm 16l btw. I've been told that i look exotic but i think i look weird why would people look/stare at me if i was hot?
