Thanks Kelu.
All I have is a 'before' picture of the valve cover,

And a shot of the engine with the valve cover off.

As far as removing the valve cover, you just take off the spark plug coils, remove the connectors from the cam position sensors, undo the oil vapor line, then loosen the 11 bolts holding it on (they self-retain after loosening all the way). It may be a little sticky, and the o-ring might stay with the engine, (see the one around the spark plugs in the photo), but it isn't too hard to do. Just clean and put the o-rings back on the valve cover before re-installing.
As for the polishing, I bought this polisher,

The valve cover didn't come out real great because the aluminum alloy used is extremely hard, and is roughly cast, with lots of surface cracks and rough texture. To do it right, I should have sanded it down first, but I didn't have the proper tools for that so I got lazy.
I'm thinking about powdercoating it now with a clear candy green like this.
