The only thing I have found is to display it on the thumbnails with the tool tips
By tool tip you mean the pop up shown when the mouse pointer is over a thumbnail?
If yes, you may find the extra thumbnail labels useful.
Go Edit->Preferences and select the Contact Sheet pane. In the middle section of the dialog, on the right hand side, you can activate up to 3 extra labels.
(Name +1 Label, Name +2 Labels or Name +3 Labels). Fill in the information you want to see in the Label 1, 2, 3 fields below it. Use the button Variables... to pick what you want in Label 1, 2, 3. I currently have mine set to {w}x{h}, {model} {serial}, {date} {time}, but I change them if I want different information.
The file name is in the preview window title bar. You can see shutter speed, aperture and more in the preview window side panel (the Info section), but it is not shown in full screen mode.
