Welcome to IDO. I am also not located in the Omaha area so don’t have any personal experience I can share with you. Here is some links to some resources NE G&P has put out that might help you as far as best locations for targeting your species of choice.
As far as tactics go I think it is important to consider that nearly all of your bodies of water with quality fish there in the Omaha area are going to receive considerable pressure. I would do my best to try to fish during peak feeding times around sunrise and sunset as often as I could and I would fish the areas that pressured fish are likely to try and retreat to and some anglers may be hesitant to fish, thick cover, heavy weedllines, ect. Hopefully there is another member more familiar with the Omaha area that could chime in but good luck to you.
