Door card removal?

There are 7 plastic push pins that hold the door panel on. Your first photo shows where the pin attaches, they mount to the door panel, and push in to the black sleeves highlighted in the other photo. Also 4 bolts for the door pull, one in the door handle cup, and one towards the rear of the door panel, underneath a trim piece.

I would start at the top right, once you get the first one off the rest come pretty easily. Yes when you are putting it back on, just line it up and push.
