The alt should not have PS fluid in it. That will eventually cause it to stop working. As far as the battery light and dim lights, it sounds like it is getting close to happening. You need to get the leak fixed soon or you will be fixing the leak and replacing the alt at the same time. If you fix it now, the alt may last a lot longer for you.
As far as the brake lights, I doubt they are related. On the top of the brake pedal (under the dash) is the brake light switch. Make sure it is properly adjusted. If it is, check it for continunity when the switch is depressed. If there is continunity, the switch is bad.
Let me know what you find or if you have other questions.
