Nortcan, since those pins are small, 1/8" or so [3mm?] I'd try bending them to do what adjusting you need to do. What I'd do is find a piece of 1/8" or 1/4" pipe and slip the pipe over the pin, and use the leverage of the pipe to bend the pin.. But the suggestions of heat are correct. The pins will bend easier if they are heated to almost red, a dull red, then gently bend the pin, using the leverage of the described pipe/pin extender.
Now, I think you covered this, but I want to make sure.. Does the door fit perfectly to the stove opening when the door is NOT on the pins? Said anotherway, is the door warped? or is the door a perfect fit, and the hinge pins causing the miss-fit ?? Is the curve of the stove a different curve [radius] than the curve [radius] of the door? If so, your gasket seal is the way to fix it.
I think you said you decided to use some gasket material [rope gasket] to fill and seal the remaining gap in the door, to me this implies that the door doesn't fit the front of the stove correctly.. and I think your use of rope gasket is the best and correct way to seal the door.
As for your heat shield, spaciing it out from the wall like you describe is correct, but you mentioned a lower heat shield sitting on the floor.. you want to leave a 1" or so gap at the floor, this will provide better airflow behind the shield.
I like your little stove, and am looking forward to the heating/opperating reports next heating season..
