Kim,
I've had both doors apart multiple times to fix the lock pop-up button, do my stereo install and lube the window mechanisms. It's not a horrible thing to do but you do need to go slow. There are lots of screws and using an actual upholstry pulling tool can be helpful although I don't have one and it wasn't necessary.
The clips and screws are available from most of the regular parts places on line and the pop up on eBay as well.
It will be fun to see what's causing the noise. It always makes me smile when I find something that's easy to fix, but at the same time, makes me wonder how in the world did it get like that in the first place.
