Answer 1

Is it also possible to open this stuff programmatically?

Yes:

    Intent in = new Intent(Intent.ACTION_MAIN);
    in.setClassName("com.android.settings", "com.android.settings.TestingSettings");
    startActivity(in);

You just need to watch logcat output to learn what this magic combination actually opens:

I/ActivityManager(31362): START {act=android.intent.action.MAIN flg=0x10000000 cmp=com.android.settings/.TestingSettings} from pid 4257
