Using Outlook 2007 SP2
Is it possible to specify multiple recepients but only send the
attachments to one recepient and the file names of the attachments to
the other recepients?
This way all folks see the e-mail date/time stamp and file names w/o
actually bulking up their inboxes unnecessarily

No, not out of the box. You may be able to write code to do it.
