Which is right and intended. This was my bad. Pleas apologize for the
inconvenience.

To be really specific, there are even more directories. Please consult
the file system hierarchy standard for more informations.

This is also intended. There can be any directory-layout in this dirs.

It's questionable if you want to save the auto-saved playlist of parole,
but the place is right for its storage (one could argue that .config
would be better suited, but for this we would need to discuss if a
playlist is config or application data).

Because xfce (and therefor xfwm4) uses xfconf ;) This doesn't mean that
other applications don't use those backends, like gvfs, gstreamer,
pulseaudio, or the other GNOME stuff you may use.

That's wrong. xfce honors this settings. They override the default from
the current theme.

~/.Xresources is _not_ ignored, see below. Also xfsettingsd is build
against fontconfig, so it depends on your /etc/fonts/*.conf if it checks
for ~/.fonts and such dirs.
For the QT-part it's important that the Trolltech.conf file has the line
"style=GTK+", which will tell QT to use the GTK-settings, which are set
by xfce.

If you read /usr/bin/startxfce4 closely you will see that different
files will be sourced, some of them could even be user supplied. Those
files can source other files, too. The default looks for:
- $HOME/.xserverrc
- $HOME/.xfce4/xinitrc (deprecated, only for compat)
- $XDG_CONFIG_HOME/xfce4/xinitrc
- $HOME/.Xdefaults
- $XDG_CONFIG_HOME/xfce4/Xft.xrdb
- $XDG_CONFIG_HOME/xfce4/Xcursor.xrdb
- $HOME/.Xresources
- $HOME/.Xmodmap

"$XDG_CONFIG_HOME" is either set to a path or defaults to "$HOME/.config".
