I am struggling with formatting footnotes.
I am not sure where you are encountering problems, but one resource I like to use is the Purdue Owl. This link will provide you with some tips for working with Notes (as in footnotes) and how much of the publication details goes into the note and what is in the bibliography.
What does the formatting of CMOS look like - starting with the title page?
The Purdue Owl General Format page provides details and some screen shots for you.
