The ballast is simply an inductor.  The wires are interchangeable.

> Also, the ballast itself must be grounded. Does this mean one neutral to the lamp and then also paralled off and secured to the ballast metal body?  I hope I don't sound too confusing.

If you have a three-wire cord, connect the green wire to one of the 
mounting screws.  Otherwise leave the case electrically isolated.
