No, Ardour just runs as a slave to Jack, and Jack defaults to 48K if you
don't tell it to do differently. Use qjackctl or the command line
version, like:

jackstart -v -d alsa -r 44100 -d hw

and you should be alright. (Please check the command above. I'm doing
this from memory.

Use qjackctl or qjackconnect to hook it up.

Use kaconnect to hook the MIDI up to something. (Maybe...) ;-)

Usually alsamixer for many sound cards. Not sure about yours.

Ardour is just a Jack app. Anything that works with Alsa and Jack will
work with Ardour.
