Where can I find xorg.conf documentation that tells me what device names etc. one can use?

The man page tells me about the format of xorg.conf and what all the sections are etc. but doesn't help in the slightest as regards how to configure actual hardware.

I'm specifically after mouse configuration information, like which Driver I should use for a Logitech Marble Mouse and what Option settings are available.

I'd really like fairly general information though as I may want to set up another (Kensington) multi-button mouse as well.
