The first sound could be almost anything from a vacuum leak on to a bad fan clutch. Does it do it all the time? Only when cold? Any other noises at the time?

Brake problem sounds like the ABS sensor problem that is caused by rust under the sensors. It causes the ABS to activate because of a weak signal from the sensor. It's not a hard fix if your mechanically inclined.

Sounds like it's time to get it to a shop. It could be a bad front wheel hub as well. The grinding makes me think that way. Not real hard to change if you want to DIY. However from the sounds of it you need to find a shop.
