I forgot to add that I think it should include the Arrow and Flash comics since I believe they are canon to the two TV series. I've only skimmed them and this is off the top of my head so forgive me if I'm not 100 percent accurate, for instance:

Fall 2009 - Laurel begins sleeping with Tommy. November 2010 - Laurel begins working at CNRI. In the comic it states this event is 2 years before the start of the series, and 6 months after she graduates from Law school which I believe is May.
