IIRC You're supposed to drop the windows a tad prior to putting the roof up to prevent the seals inadvertently pushing down on the window when closing.Even if you could get them to drop with the door handle, I can't see what it would help as the quarter glass is fixed and so is the frame for that.
Yes, but I'm presuming this is more to prevent the roof seal catching the window at the (what would be) B pillar end at the wrong angle and potentially damaging the roof seal, or worse breaking the window glass! Not sure though.IIRC You're supposed to drop the windows a tad prior to putting the roof up to prevent the seals inadvertently pushing down on the window when closing.
