Answer 1

No, the cl_device_id parameter to clGetDeviceInfo should be one you got from clGetDeviceIDs (which, in turn uses a cl_platform_id you received from clGetPlatformIDs). The device ID might match the one you see in Catalyst Control Center but that doesn't matter for anything; you can't (or at least shouldn't) access the device with a hard-coded ID and should only use IDs returned from the runtime.
