Option 2 or 3 are best.
You only need to listen to one session daily. When you do the exercises along with the listening it should take you no longer than 45 minutes per session. Give the weekend a couple of extra session. Make a start and continue during the week. If you only have 30 minutes listen to the tracks and do the suggested exercises the next day. Listen to the exercise follow up information after doing the exercise. This would take 20 to 30 minutes a day. Even if you can't do them everyday do it on the days you can.
You can always play with the PhotoReading step when you have a couple of minutes to spare every day.
