In shallow water, just about any fish is likely to be rather skittish, and not willing to bite.
Sounds like the pike you saw were gar pike, if in fact they were distinctly needlenosed. Minnows or small silvery spoons are your best bet for them. But again, with such shallow water and them being so openly exposed to you, they may be too scared to bite.
Catfish like stinky baits...fresh sucker meat is popular, chicken livers are as well.
Walleye...not a fish I should even attempt to give tips on but not likely to be in the same places now as they will in the fall.
That's all I got.
