First of all bank one is on the bank of cylinders that include cylinder #1. Sensor one is on the exhaust manifold/ piping before the convertor and sensor 2 is after the convertor.
Throttle position sensor is on the throttle bidy I suggest taking it in for that one as it has to be aligned perfectly.
But you can change the sensors youself just let the exhaust get hot first
