Check for screws - there shouldn't be more than 2 or 3, and they shouldn't be too hard to find. You'll need a phillips head for that most likely. If any of these screws go through a piece of plastic behind the door handle or anything along those lines, rather than the panel itself - you may have to remove that seperately. Do so now.
Then use a flat head to pop the clips out of the door - simply slip it between the panel and the door frame and twist. There should be anywhere from 4 to 10 of these, I cant imagine there'd be more or less. There will NOT be any along the top edge of the panel. At this point you'll be able to see if you missed any screws - if you did, take them out.
Now, you'll need to unclip any switches or whatnot - this will be a bit fun, as you get to work blind. Electric windows/locks will have clips, if your speaker is in the door panel, that will have a clip - etc. Feel around, you'll get them eventually.
Now you get to pull the panel off - not a big deal. It should be hanging from a lip at the window seal
At this point, you'll be looking at a door frame, but it will have a plastic sheet covering it, which will be held on by a tacky glue - just pull this off, but try not to make a mess - this stuff isn't the most fun to work with, and it will stay sticky - so don't worry about needing to go out and buy more. Just try to keep it clean and you should be fine.
From here you should be able to get the paper out - if you can't, well, you're not looking hard enough, because you should be able to see the door's innards.
Reinstallation is the reverse of removal. Be sure to test all the electronics before you screw the panel back down - just in case you forget to clip something.
