The P0410/1411 are related to the secondary air system (both banks), implausible signal.

For the O2 sensor problem, try swapping the forward sensor (that you just replaced) with the forward sensor on bank 1, and drive the car a while to see what happens -- see if the fault moves to the other bank (B1). There could be a problem with the new sensor you bought -- it's happened before to people.
