Right now the capability to input your own logo is not available. The Moldflow logo in the bottom left corner of the viewer window is built into the application and can't be changed.
As for part information - I would suggest placing that into the Study Notes by going to View->Notes or right clicking on the Study you are going to export and selecting "Study Notes..."
These can then be viewed in Communicator by going to View->Notes and a panel will appear in the bottom right corner.
