As you're using Asterisk 10, I'm going to assume you're using ConfBridge.

You can use ConfBridge's DTMF menus to allow a participant to change
their listening volume.  This should only affect the audio that the
participant hears, and not the other participants in the conference -
regardless of whether or not the audio originates from the same source.

[bridge_user_menu]
*1=increase_listening_volume
1=increase_listening_volume
*2=decrease_listening_volume
2=decrease_listening_volume

For more information on setting up DTMF menus and associating them with
bridge users, see the ConfBridge article on the Asterisk wiki:

No, that's fine.  ConfBridge allows you to control the listening/speaking
volume of each participant.  See above.

If you wanted to stream your sound from a source other than MOH, using a
Local channel may be appropriate.  I'm not sure how a Queue would help here.
