The file manager is pantheon-files, so simply running
works. Because pantheon-files does not run in the background by default and generates plenty of terminal output:
[_LOG_LEVEL_INFO 11:43:27.546677] Application.vala:155: Files version: 0.2.1
[_LOG_LEVEL_INFO 11:43:27.546761] Application.vala:157: Kernel ...
Symlinks might be what you are looking for.
Delete (or rename if you want to keep the files within) ~/Downloads folder.
In terminal type out the equivalent of:
ln -s /media/Documents/Documents/Downloads /home/pablo/
This would create a link to your windowsdrive, such that when you use your ~/Downloads folder it would be as using /med../Downloads.
Maybe try something like Data Crow?
I was never much satisfied with the "iTunes" approach to this, wherein you get an app to "Import" some "Library" of items that you can then tag and search and comment on.
So I always ended up hacking together my own solution. Except on Haiku or OSX > 10.8, which get tagging right (in my opinion).
Poor man's solution
After modifying ~/.config/user-dirs.dirs you have to run
for the changes to take effect. If this doesn't work for you, try
xdg-user-dirs-update --set DOCUMENTS /media/charles/4ACE6B6ACE6B4D6F/Users/Charles/Documents
to explicitly set the documents folder to your desired path.
Simple answer: No. Luna's version of Pantheon Files depends on libraries that are not available in Freya (or, to be more specific, the corresponding version of a library is not available anymore).
Pantheon Files has undergone a lot of development since Luna anyway, so you would be losing crucial bug fixes.
When searching for Gwenview I came across Eye of Gnome (eog).
It doesn't have as many editing tools, but it also doesn't have most of the issues I ran into with Photos. (The file order is wrong, but you can open a slideshow. And you can open multiple images in the same window, which makes that less painful).
You can ...
You need to create a .desktop file and put it inside ~/.local/share/applications.
To do that open any text editor and modify the following code to make it work with your app. Please modify the Exec= line with the correct command to launch the app. You can add an icon as well, for that you need to save the file somewhere and add the full path.
Save the ...

Copying from Files (pantheon-files) and pasting to LibreOffice does this indeed. You might want to file a feature request in pantheon-files: https://bugs.launchpad.net/pantheon-files/+filebug
As a workaround, you can drag&drop pictures from Files: this works with LibreOffice (could not test with Crossover though).
You can change the behaviour of program such as gedit that use the Gtk+3 filechooser by changing the dconf setting org.gtk.Settings.FileChooser.sort-directories-first using dconf-editor or from the commandline. (gsettings set org.gtk.Settings.FileChooser sort-directories-first true).
The best tool I've found so far is DupeGuru. It's free and there is a PPA for Ubuntu. There are also specialized versions for picture and music files.
sudo add-apt-repository ppa:hsoft/ppa
sudo apt-get-update; sudo apt-get install dupeguru-se dupeguru-me dupeguru-pe
