As it states in the course manual, start by listening to the first audio lesson. Then go through the chapter that corresponds with the audio lesson. Go over the lesson again if you feel like it, or you can go on to the next. And, It's not a bad idea to listen to your Personal Genius paraliminal to get yourself relaxed and ready for learning.
The Paraliminals in the Million Dollar Vocabulary integrate the vocabulary words at a deeper level. Go ahead and listen to these right away, at least once a week while going through the course. Because most people learn more effectively taking breaks every 20 to 30 minutes or so, just one or two lessons a day is probably the best. And it's fine to take a day off to do your creative writing.
How long it will take to go through the course depends on the individual. You might want to go over the same audio lesson a few times, and take the quizzes over again, or you might listen to each lesson once, and then go back to the course in a month or two. It's really up to you.
And, it might not be a bad idea to start your creative writing course at the same time you start your Million Dollar Vocabulary. Try to notice differences in your vocabulary when you started the course, and then notice any changes in your writing after you've completed the Million Dollar Vocabulary.
