Okay, I created a "New group" called 'Specs' and configured it to be a Tab. I then disabled my custom node-product.tpl.php theme so I can see the default UC output and I can't figure out how/where to get the tab 'Specs' to appear on my products.

I'm sure I am missing something really trivial. Any help is appreciated. Thanks!

EDIT: Ahhhhh I found "CCK Fieldgroups Tabs" at the bottom of admin/content/node-type/product. Looking into that now...

EDIT: Okay, so I see a new field appears in my "Manage Fields" page, but there is no configure option for it. So now I'm stumped again

EDIT: When I add a name to the "CCK Fieldgroups Tabs" section of Content types > Product > Edit, I can get that name to appear as a tab, but I can only add one name here (so only 1 tab) and I still don't know how to add other fields to this tab. So this can't be the proper method. I've already created other "New group" fields and configured them under "Display fields" to be "tabs" but they never appear as tabs. It would be nice if I could just drag the list of fields into a child-field of my Tab group fields, but there doesn't seem to be any sub-category or child-type dragging possible....
