Answer 1

You might be helped by the timelines listed on the following page
http://www.state.gov/r/pa/ho/time/

Or try another, starting here:
http://future.state.gov/when/timeline/1801_timeline.html

Or the pages indexed here:
http://history.sandiego.edu/gen/classes/diplo/176.html

If you want a BOOK-length treatment, the classic resource is *A Diplomatic History of the American People* by Thomas A. Bailey

Answer 2

I'm not sure what you mean by a "listing", but for a good survey I recommend Walter LaFeber's The Amercian Age. LaFeber was probably the most eminent scholar in the field until his retirement last year. He was a history professor at Cornell. His perspective is somewhat liberal, but not radical by any means. (He's not like Chomsky, for example.) Check it out.
