So I think that what you need to do here is to keep a data structure
associating the hal udi and the mount point, e.g.

 struct {
   String udi;
   boolean is_mounted;
   String mount_point;
 } Volume;

Note also that these two properties are updated as a single transaction,
e.g. atomically... this means that the PropertyModified D-BUS signal
actually tells your process (the client) that they were changed at the
same time... libhal, IIRC, doesn't tell you this though... 

However.. you should just keep the mount_point around. Wouldn't this
