Jack is showing what ALSA tells it to show. And ALSA manages the envy24
chipset which always has 12 inputs and 10 outputs, even if they are not
connected to anything :-( I know, could be better :-) The analog inputs
and outputs you want to connect to are the first four ones, just ignore
the others (except for spdif, of course). I don't think there is an easy
way to change the names displayed. 

You can use the envy24control app to control your chipset in more detail
(part of the alsa-tools package).

In general you don't need .asoundrc. Just don't use it for now.

As to ardour I imagine you are creating a new session first? If you
don't do that, you can't add anything at all. Maybe you did that the
first time you launched it but forgot afterwards?
