Only thing I would do is set Screen 3 to Auto (the advice of most pro-reps) unless you have specific cases where the subject meets one of the specific criteria. I actually use Case 4 but changed the Tracking to -1 so it sticks on the initial subject better, but that speaks to the small birds I tend to shoot.
It takes a couple weeks of shooting to fine tune, and as I said I've enabled the control wheel on the lens to allow me to switch between focus points. I've used AF Menu 4-Limit Focus Methods to eliminate all but Face Tracking, Expanded Area and Large Zone Horizontal as those are what I've found useful and it doesn't require me to move through things I'll never use.
