Like Nostalgie said, go to %appdata%\Electronic Arts\Dark Age of Camelot\phoenix and copy the Charname-41 files.
You also can setup a global standard layout, that will be applied to all new characters. In that case: 1. setup the UI on 1 character & log out 2. go to %appdata%\Electronic Arts\Dark Age of Camelot\phoenix 3. Open the characters config file (charname-41.ini) 4. Copy the contents 5. Go into your DAoC installation directory 6. Look for the file defaultXXXX.ini and paste in the copied settings
XXXX stands for the resolution. If you are running 1080p (1920x1080) the files name is default1920.ini etc
