Comma usage after ((In|By|As of) followed by (date))
e.g.


 * In October 2010 something happened.
 * As of October 2010 this thing has been true.
 * By October 2010 something happened.

Do you put a comma after 2010?

Comma usage before with
e.g.


 * Sainte-Anne-de-Beaupré stands in a rolling agricultural country, with the foothills of the Laurentian Mountains in the background.

Can you remove the comma before "with"?
