You can just right-click on the Documents icon and choose Make Link. Then just
drag and drop your new link to the desktop. You can right-click on your new link
and rename it, removing the Link to part. This just takes a few seconds. I did
the same for my music folder because I listen to music quite a bit.
As far as editing the menus, you can right-click on the menu and edit the menu.
The problem with that is you can only edit the System and Applications menus. I
don't know why they didn't include the Places menu in the editor.
You could try to rename the Documents 2 folder and call it Documents.
