Is there a way I can delete at&t's shop graphics, shop multimedia, shop applications, shop themes, cellular video, shop music, musicID, etc?

I never use it
I can't use it because I have a 9530 unlocked on at&t
and it's kidnapping my memory. I'm trying to save my phone because buying a new one.

I'm not sure where to look either. Help please!

They don't take up any memory. They're just web shortcuts delivered via Service Book.
Hide them.

(If you delete them, they'll likely get pushed back to your device shortly afterwards.)
