You might try some lube on the sliding metal track to get rid of the grinding. The only other thing I can think of for the grinding would be if the bottom edge of the door was rubbing against the body. My old hatch had that issue, but it didn't make any noise.

The squeaking is might be the hinge, or it might be the small pin the metal track is attached to. I don't know anything about the hinge, so I can't help you there, but the pin can be gotten out with a small hammer. Lube it up and put it back in.

There aren't any moving parts inside the door associated with the opening and closing of the door, so I don't think you need to remove the door panel.
