I want to get an iPhone, now what?

Let me just say I'm completely new to this whole "smart phone" thing. I've had my trusty little flip phone for about 8 years, and now I finally think it's about done for. I want to get an iPhone, but I have no idea what to look for, what all this iPhone 4 or 5 or 6 business is or what it means, and what plan to get. If anyone knows the inside and out of these little phones and doesn't mind helping an old fashioned lady out, I'd really appreciate it. I need a relatively inexpensive plan that will allow me to do what I need to do (get on the internet, check emails, etc.) A few friends of mine said something about group chat, does that come with it or is that an app(?) you download or something? Oh and they mentioned the cloud. What is that? Clearly, I'm lost on this subject.

Is it worth upgrading my iPhone 5 to an iPhone 5s?

My iPhone 5 keeps glitching by randomly turning my music on and off and turning my siri on. It'll start doing things on its own. I tried restarting my phone but it makes no difference.

I stole a iPhone case from Target?

This incident happened last year, around Christmas. This was a terrible mistake. I'm not a bad person and did this and I felt really bad since this incident. I'm a 15 year old. Nothing happened to me, they just followed me around the store. I don't think they would press charges on me for a iPhone case(I got scared and dumped it outside), my Dad worked Loss Prevention and he said nothing will happen. He thought I shouldn t steal and it was bad of me, cause I'm a good guy. And I wouldn t ever be a guy to do such a sin. And this is in my head and I can't get it out…

I want to presue being a cop some day.
