Swayam Chouksey: Thank you - I tried what you suggested, but it doesn't look like home page components are displayed on the Chatter tab.
Pritam Shekhawat: Thank you - I understand the limitations of Chatter Free. What I'm trying to affect is the display on the Chatter tab.

That's the avenue I'm trying to explore here. I'm not looking to grant my users access to any more data than the Chatter license allows.
