That might be the step Alan is missing. Try changing the polygon's signal 
name to GND. Eagle should then merge the ground traces into the ground 
plane, and isolate around the other sigs.

I have used polygons to make ground planes also, I would just rename the 
polygon as GND same as all of my GNDs, I use a polygon around the whole 
bottom layer.
Actually, I have only done it twice but they have turned out nice.

Although I don't need a polygon now, I have used polygon to
create a groundplane in the past. However, when doing so,
I could not figure out how to merge the filled polygon
with the adjacent ground trace. Eagle always left an etched space
between the two.
