Add the offending languages under language in control panel, then delete them and they will be gone from the notification area.
The keyboard layout (in Windows 7 at least) is contained in the registry key
Preload determines which keyboard layouts are present in the keyboard switch button (on the bottom right of the taskbar), and the number determines the ordering.
The REG_SZ item "1" contains the first layout, "2" the second, etc.
The article Windows Keyboard Layout lists most keyboards ids.

It would be interesting to know what your registry contains at these locations.
