Squealing brakes is one of the drawbacks of higher-quality brake pads. If it gets worse in humid conditions, and the noise goes away when the brakes get warmed up, as in city driving, there's not much chance of getting rid of all the noise but there are things that will reduce it. It has to do with the surface finish on the rotors, and scrubbing rust off the points the pads contact to hold them in place.
For the stalling, the battery might have been disconnected or run dead recently. If so, the Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
