1) 1887. "When the National League and American Association used the same rules starting in 1887, two changes took place. Third and first bases moved seven and one half inches, toward second base, so that they were entirely in fair ground. Also the 30 yard mark fell upon the back rear corner first and third base."

2) No. "The first and third base bags shall be entirely within the infield. The second base bag shall be centered on second base." OBR 1.06. So the base points are a perfect 90 foot square, but the centerfield corner of the second base bag is ~10.6 inches hopefully East-Northeast of the second base point.
