answer 1
On the merit of the previous answer, I went ahead and bought a soft-copy (for my Olivetree.com software) of the HarperCollins Study Bible. I immediately compared it to the HarperCollins Bible Commentary I bought from CBD (thank you very much). The scholarly positions sometimes overlap but every commentary is unique and formatted for a study bible format. All the introductory articles are rewritten even if they are authored by the same writer as contributed to the commentary.
Example: Richard Bauckham wrote the notes for 2 Peter and Jude for both the study Bible and the commentary; but the format for each is appropriate for the purpose. In the commentary, the comments are laid out in sections while in the study Bible they are presented verse-by-verse. He took no shortcuts by recycling anything he had written in the other book. It is true also for the other few writers who commented in both books.
The scholars who contributed to these resources are the top experts in these books. Bauckham, for example, wrote a marvelous commentary on 2 Peter and Jude for the Word Biblical Commentary series; and David Aune wrote the most respected commentary set at CBD on the book of Revelation - and he contributed commentary and notes for the HarperCollins resources. It's a privilage to have such scholarship collected into a single resource like the HarperCollins Study Bible and the HarperCollins Commentary.

answer 2
There is overlap between the study notes in the study Bible and in the commentary. The commentary will have a fuller treatment of passages. The two books are meant to complement each other.
