confused about power

Gordon: I have lots of old USB cables with ferrites on them, if I clip one of those onto the black cable which end should it go near ?

AllObjects: I powered the shift register with 3v -- should I switch that to 5v ?

AllObjects: I am interested in the 'decoupling' could you please re-state it more concretely ?

Here are more pictures, a better description, a parts inventory, and the code I used

Thanks,
Al;
