Although the speech rate is managed by Orca, AFAIK, the speech rate
value is related to the specific speech engine.
So in case you're using espeak, the speech rate is mapped with words
per minute as is described here:
http://espeak.sourceforge.net/speak_lib.h
There, you can see the following line:
      espeakRATE:    speaking speed in word per minute

The magnifier settings are managed by GSettings, and you can see all
the available settings described in the
"org.gnome.desktop.a11y.magnifier" gsettings schema.

In the "org.gnome.desktop.background" gsettings schema you can find
background-related settings but I'm not sure if these settings suits
your needs or if you'll need to make some modifications on the Adwaita
(or whatever theme is used) theme description. So ping me back if you
need more help on this.
