You have a strange mixture of packages. If all you're trying to do 
(bluetooth-wise) is use your bt headset, those are all the packages you 
need:

- bluez-gnome
- bluez-utils
- bluez-audio 
- libbluetooth2

'bluetooth' is just a metapackage (empty package that pulls in all 
bluetooth-related things ) bluetooth-alsa is a part of an older project, 
not related to this ML. 'bluetooth-audio' - ditto. gnome-bluetooth - I 
have no idea. gnome-vfs-obexftp - that's for browsing remote filesystems 
over bluetooth. libbtctl4, libgnomebt0, libsbc0 - obsolete libraries

No, that's not true. Since you're already paired with the Headset, all you 
need to do now is start playing music :) ( and possibly switch the audio 
service on )

Cool! that means you're paired already. No need to do any 'hcitool scan - 
hcitool cc' magic anymore.

The first time I ran

That was the pairing process. As you say, a one-time phenomenon.
