Barb,
Go to Sew-Classic and look at the lighting section: {

You can use either the third or fourth light down in the center row depending on weather or not your machine has the cut out for the light behind the inspection plate.
Also for a new wiring block look here; {

You'll need the center cord block assembly in the first row.
As for the case I can't help there, but it will fit in a standard Singer cabinet.
