Fill Flash in Manual Mode on a Canon


I always shoot in manual mode on my camera, too addicted to the control I guess. I have a 5D Mark III and a Speedlite (550EX) and Yongnuo 569EX II. I will likely be using an 85/1.2 and I am looking for the best way to leverage the on-camera mounted Speedlite based fill flash in eTTL mode for outdoor back-lit portraits. That is, a nice balance of background exposure and fill on the subject. Below is my approach and for use in manual mode (e.g. not Av or Tv mode) and I would like to get feedback if I am missing something and/or anyone has a better approach:

1) Meter the entire scene.

2) Adjust shutter speed / aperture / ISO based on what look I am trying to get with the goal of setting the overall scene (subject plus background) exposure anywhere from -1/3 to -1 stops.

2) Use the Speedlite in eTTL mode adjusting the FEC to taste which seems that seems to be somewhere between 0 to -1 stop (looking for any guidelines here).

However, it seems I am missing something and/or making it more complicated than it needs to be. For example, if I am adjusting everything down up to a stop, why do I need to do that at all? Help that neuron fire in my brain that will help me understand. I would love to hear the steps any of you have followed to use fill flash in manual mode.
