Here's what I do, whether it's with my Frogs or with toe cages.
Unclip my right foot before I need to stop.
Pedal with the arch of my right foot if I need a little more oomph to get to my stopping point.
Put my left foot/pedal at it's lowest point with my weight on it and dangle my right leg IN FRONT of the right pedal. Usually my butt is off the seat at this point.
When I stop the right foot hits the ground first, then I unclip the left and put it on the ground.
I think the only reason I put my right foot down first is because I'm left handed and prefer to control the bike with my left foot.
