Can I buy the Apple iPhone 6s SIM-free in stores?

I'm going to be purchasing the Apple iPhone 6s very soon, and I will be buying the SIM-free version. Is it possible to go to an Apple store and purchase the SIM-free version? Or is the SIM-free version only available online? The google searches I've done have given me confusing answers…

Is your iphone spied on and whatever you do on it someone knows exactly what your doing?

For example I know Facebook and things like that are monitored, but on an iphone the apps such as the notes, the weather, the pictures, the videos maps and mail etc, are they monitored too and spied on by people who are monitoring everything you do on your iphone? If just say you wrote something on notes and deleted the note, is that note stashed somewhere in a folder or cache for others to spy on and retrieve who are working behind the iphone?

Imessage/iCloud syncing problem?

So I just updated my iPhone 5 to iOS 9.1 and I had I message on. When it finished updating it synced my iMessage to my moms phone and my parents iPad. I quickly unchecked their numbers and switched off iMessage so they won't get my messages. But will they still have my previous iMessages or will it not show up since I unchecked it and turned off iMessage. I'm scared?

I broke my iphone 6 plus and need to retrieve photos?

At first i just messed up the lcd screen. My notifications were going crazy on the phone, so i turned off the phone. Now the phone does not power back on. I'm pretty sure i did not set up my photos with icloud like i did my contacts & such. And i really need the photos because they hold a ton of sentimental value, but my phone won't power back on. Is there anything i could do, take it to apple? Have it repaired? What could i do? My new iphone is on the way.
