How you can change you're gdm gtk3 theme with fedora 15.
Prerequisite: gnome-tweak-tool and a terminal (gnome-terminal)
Open gnome-terminal:

Code:
su -
( insert password)
Now we are root and the first step is to install gnome-tweak-tool if you already did this skip this. Install gnome-tweak-tool

Code:
yum install gnome-tweak-tool
Now we make the gdm user available to make changes:

Code:
# xhost +SI:localuser:gdm
If you did this right you get this message:

Code:
localuser:gdm being added to access control list
Next we will fire up gnome-tweak-tool

Code:
# sudo -u gdm gnome-tweak-tool

This will start gnome-tweak-tool as the user gdm (sudo -u username will start the application as designated user). Now we can change the interface gtk+theme, icon theme and cursor theme to whatever you like. Don't forget to change windows current theme to what you want.

How to change gdm login background:
Code:
# sudo -u gdm gnome-control-center
Here you can change the background

And when you're done exit the gnome-tweak-tool or gnome-control-center and type:
Code:
# exit
(ps the # sign is the sign you're running the command as ROOT don't copy it!!
