Should I continue studying Profit Singularity at the same time as Facebook, or will the Facebook modules cover everything I need?

The Facebook modules cover everything you need for Facebook. If you're running YouTube ads, you can continue with Profit Singularity as well. 

For more insight into getting started with Facebook Ad Vantage, refer to the program video Introduction to the System & Opportunity
