The braking noise is due to a combination of warped rotor and grooves worn into the caliper's mounting pads. Those grooves form most commonly when do-it-yourselfers slap on new brake pads without using special high-temperature brake grease on those surfaces. Usually the noise can be solved with just a machining of the rotors. If they are too thin to remain above the published legal minimum thickness, they will have to be replaced.
Creaking must never be ignored. Have the steering and suspension systems inspected at a tire and alignment shop. Common causes are deteriorated control arm bushings and worn ball joints. Worn bushings are not exactly a safety hazard other than they can cause unstable or unpredictable handling and steering response. Creaking from a worn ball joint is a warning it is about to separate leading to loss of control and a crash. That noise could go on for months, or the part could fail very soon.
You will need someone to listen to the engine noise. Most mechanics can tell what the cause is just by hearing it.
