If your going for cats I would fish around the light house area, but basically anywhere in the lake is good for them. Since your in a boat I would reccomend buying some minnows and fishing around the floating islands for crappie. I havent fished out there yet this year, but we always had great success in that area for crappie. And as a general rule we would always fish around the light house area for cats, but they can be found nearly everywhere.
Livers or night crawlers for cats, and minnows for crappie.
