I made it the easy way...

Here is how I made it:

To change the Background-Image of the login-screen

--> /home/cynin/buildout/src/ubify.cyninv2theme/ubify/cyninv2theme/skins/images

- replace the file login-bg-team.gif with one of you pictures

To change the favicon for your browser

--> /home/cynin/buildout/src/ubify.cyninv2theme/ubify/cyninv2theme/skins/icons

- replace the file favicon.ico with one of your icons

I think this is much easier to do than to hack in css-files.

Hope this helps!
