What kind of set up are we talking about - what machine and frame are you using? Can you post a picture of the back of your machine and what you are talking about with the cord?
As for the light, you'll want more than just a little spot light.
I'm in a former church and lighting is always an issue. The wood on the high ceiling just sucks up whatever light there is. I'm looking at having my husband and son work up some kind of overhead light bar for the machine.
