Printing and selling iPhone cases - copyright issues?

I'm looking in to setting up a small business involving printing iPhone cases.

As a complete newbie to business and self-employment, does anyone know what copyright laws there would be attached to this?

I would guess certain pictures / logos could not be used without the authorisation of whoever owns them. How could I find out whether something is copyrighted or free to use?

NON-APPLE BRAND iPhone 5 lightning charger?

I have had nothing but problems with the Apple Chargers. I've had three in one year and they've all broken after getting that wrinkle right by the plug-in. I want to know of a good non-apple charger (or I guess more specifically, a USB cord.) I don't really care about the price, I just want to know it will last me a long time.

Will my family members get the same apps I download?

My mom and brother and I are getting a shared data plan for our new iPhones, and I've heard that there's something about everyone getting each app that anyone in the plan downloads. Is that true? I don't want to have to have all of the games my brother will download, and I don't want my mom having all the social media apps I download lol

Pittsburgh Penguins iPhone 5 Case?

So, I'm a HUGE fan of the Pittsburgh Penguins, and I really really want to buy a Penguins iPhone 5 case. I live in Canada and I can't seem to find them anywhere unfortunately.

does anyone know any stores in Canada (such as Target, Walmart, etc.) where I can find a Pittsburgh Penguins phone case for around or under $20? Preferably maybe an Otter Box too if possible?

this is an example of what I'm looking for, in fact I'd buy it, I just don't know if its a reliable website:

or even any RELIABLE websites? (other than Amazon, eBay, etc.)
