Answer 1

The naming convention for WP8 app is "MyHelloWorldSampleApp_Release_AnyCPU.xap". "MyHelloWorldSampleApp.xap" is most likely a remnant from the WP7 version of your project, and should be deleted to avoid confusion.

To publish on the Marketplace, it is strongly recommended to pick the release version. The debug version disables some optimizations to work better with the debugger. Since it's not possible to attach the debugger to an application published on the Marketplace, there's strictly no point in publishing the debug version.
