You don't need 1+2. After syncing once with the sync button on the battery cover and the sync button on Dolphin, you just need to press any button the next time you play a game and the Wiimotes will automatically reconnect. Just make sure a Wii game is already running before trying to sync / before pressing any button on the Wiimote to reconnect, otherwise it won't work...
