I also use superlines with a fluoro leader - usually 12 lb or heavier unless I'm fishing Table Rock or Beaver away from heavy cover.
I like an EWG hook and 4/0 is about as small as you want to go.
Action can be anything from working so fast is skitters across the surface to barely twitching it as it drifts in current.
Using superlines I don't have to worry much about hooksets - but I do a sweep set basically.
I like all kinds of Fluke style baits, a couple that I'm never without are the realistic looking PowerBait Jerkshad for when the fish are picky, and the 4" Bass Pro "Shadee Shad" which is a Bass Assassin clone. The smaller 4" is amazing in the river and smaller creeks, and sometimes the fish want a smaller profile.
Don't be afraid to try any color you can get, either. Sometimes Smallmouths and Spots will nail a bubble-gum or pink or chartreuse bait when nothing else works.
I use lead flytying wire or solder to add weight to my hooks, weight closer to the head gives a spiralling fall, where weight centered at the bend will give it more of a 'glide".
Another thing about having a rod ready with a EWG hook like that is that you can switch to other baits easily. Unless I'm wading with only one rod I almost always have one rod ready for a fluke. If the fluke isn't doing it I can slap on a senko, a floating worm, or put a tube on there. Great setup.
