Answer 1

Here is my main activity with a button and I have set an onClickListner on it to toggle my GPS from OFF state to ON and there is no need of any permission to do this.
Tested with Android 2.2 and working fine for me.

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Settings;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class GPSONOFFActivity extends Activity {
/** Called when the activity is first created. */
Button b;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    b=(Button)findViewById(R.id.button1);

    b.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            toggleGPS(true);                
        }
    });
}

private void toggleGPS(boolean enable) {
    String provider = Settings.Secure.getString(getContentResolver(), 
        Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(provider.contains("gps") == enable) {
        return; // the GPS is already in the requested state
    }

    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", 
        "com.android.settings.widget.SettingsAppWidgetProvider");
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3"));
    this.sendBroadcast(poke);
 }
}
