I agree with all the above input, except for one thing. If bluegills is what your after, I would think a 6wt would be a bit overkill. That rod would work great for bass or carp, but gills around these parts rarely go much over a pound, and a 3wt or even a 2 wt handle them perfectly.
As for flies, most any fly will catch gills, however I seem to have the most luck with the "spider" types with the rubber legs. Their especially good to learn on, because of the weight they are.
