The rear corner ones (I think technically they would be the D-pillars?) are easy, you need to pry out and remove 4 retaining pegs and sleeves on each side from the inside (the pegs are visible when you open up the lift gate) and they pretty much come off after that. I don't know about the B-pillar moldings on the doors, there appears to be a Torx screw inside each door and perhaps you need to loosen that to remove them?
