A P0141 is for the O2 sensor perfomance Bank 1 sensor 2. If there are no wiring concerns, then replaceing the sensor should fix the SES light.
As far a the spark knock problem, may have sticking injector poppets causing a lean condition, degraded Knock sensor or even excessive carbon build up in the cylinders.
