The cables started smoking because they were subjected to excessive cranking time which would heat them up and the main reason is becaus they are of low capacity. A better set of cables would not have such occurrence.
If the brake pedal is still going to the floor, you most probably have a failed master cylinder.
With engine running, depress and hold the brake pedal lightly but with sufficient force to allow the pedal to sink if it occurs. If the pedal sinks after a few seconds, either the master cylinder is bad or you have a leak somewhere.
If the battery was completely drained prior to the jump start, the low idling would occur as the computer has lost its memory and would require some running time for it to relearn and run correctly again.
