It's included in the Fedora repository.  Just find it in the graphical
package manager or via the command line:
yum install gnome-tweak-tool

That might be the dock extension ("gnome-shell-extensions-dock" in the
repo), but I'm not sure. In general, you might want to run "yum search
gnome-shell-extension" and see if anything strikes your fancy.

That will turn off all the graphics-accelerated crap and give you
something closer to a GNOME 2 experience.  You probably should still
investigate what's going on with your graphics (that's unfortunately
above my pay grade), but it will get you a usable desktop in the
interim.
