Old roommate won't give me my stuff?

I recently moved out of my ex's parents house, and when I did I left behind all my stuff. When I went back to get it I was only given a percentage of it back. They stole my iphone, coach wallet, clothes, etc. What can I do?

Can I go to his moms work and watch the cameras to see if she has my stuff if I'm able to file charges?

Also, Before I got my own place after I left there it happened to me again, but this time I was given back a percentage of my stuff by the mother's son who keeps claiming it was all there. What can I do?

Why can't the Iphone download anything outside of the Apple Store?

After having the Iphone 5 for nearly 2 years now, I don't understand why anyone would want to deal with iphone. You can't download anything, movies, music, or apps, outside of what's in the Apple store. I'm hoping the iphone 6 will be different, if not, I'm about to switch to Samsung soon.

How to hook up my iPhone to my car? - 2

I have a 2003 Ford Taurus with the original radio that came with the car, which unfortunately is a CD player, not a tape deck, and has no visible auxiliary ports that I can see.

My iPhone 5c randomly started to turn off but then turned back on?

I was playing on my iPhone and then it went to the apple logo as if turning off, so inassumed it had died, and I was about to plug it in when it turned back on and my battery was at 86% still. It scared me because I'm a already a bit paranoid as my door randomly opened earlier, so with my iPhone being weird on top of that I'm a bit freaked out, are there any logical reasons on why it did this? I've had the phone for 2 months and it's never done this before
