Answer 1

Are you including the DLL in your appx package? That is required for the app to be able to find it.

Make sure your DLL is flagged as Content and marked to copy into the appx package.

Answer 3

In the properties for the DLL where you set the "Build Action" to Content also set the "Copy to Output Directory" property to "Copy Always" or "Copy if Newer". See http://msdn.microsoft.com/en-us/library/0c6xyb66.aspx for more details.
