I'd only take a look at those meta packages, not install them. They pull 
in massive amounts of unneeded packages. And on a minimal system I'd use 
apt-get or aptitude instead of Synaptic.

Yes but not if you use the lubuntu-core meta package as it doesn't 
depend on PulseAudio.

A lot of USB audio interfaces can't be controlled with alsamixer as they 
only have hardware mixing. Quickly browsed the user manual of the 
AudioBox and I see no references to controlling the interface from the OS.
