Writing this in my just updated Lucid installation.
As regards theme, I have never changed it. When on the login screen, after having clicked my name, the bottom pane shows three widgets: Language, Keyboard layout and Session. If you don't see those, maybe the theme you are using is broken?
And yes, with gdm 2.30.2.is.2.30.0-0ubuntu5.1+langfixes~lucid1 it's easy to change the language from the login screen. With gdm 2.30.2.is.2.30.0-0ubuntu5.1, the widget is there, but trying to change language from the login screen does not always give the expected result. That's one of the reasons for the backports.
I don't know how I would change the GDM theme, so I can't tell if there is an issue in that respect.
