Your settings are way too high.  Take a look at my render setting tutorial.

A better setting for the AA is 4 min, 20 max and set the threshold to 90 to 100%.  Don't go above 46% on the overall quality slider (for every oercent over you can figure adding hours to the render).  Tile rendering uses more memory and does not make it look any better.
