You should be able to blacklist the snd-hda-intel driver in
/etc/hotplug/blacklist. That ought to prevent the Intel HDA driver from
loading and thus leave you with just the USB audio device.
Secondly, most modern desktops are using PulseAudio these days, there's
a tool, `pasystray` which lets you select the sound device.
Finally, there's asoundrc to configure the default device, have a look
at the output of `cat /proc/asound/cards` to make a note of what ID the
device has, then add a line to your .asoundrc:
> pcm.!default {
> type hw

See http://www.alsa-project.org/main/index.php/Asoundrc for more
information.
