You can have the computer scanned for trouble codes at a nationally recognized parts store. Most will do it for free and then you will know why the light was on. As far as the pulsation, does it still do it? Did it seem like the ABS was functioning? Also, have the brakes checked for the squeal.
Finally, the noise you hear, there have been problems with the power steering pumps being noisy. If you want, remove the serp belt and start the car to see if the sound goes away. If it does, then you can start to eliminate things because the you will know the noise is coming from one of the accessories that belt runs. IF YOU DO THIS, DO NOT RUN THE ENGINE FOR MORE THAN 20 SECONDS WITH THE BELT OFF. IT WILL OVER HEAT THE ENGINE AND CAN CAUSE DAMAGE.
Let me know what you find.
