Cant help you much on the floating/paddling part of it, other than its a 2 day float. For tackle, I'd go with a medium or medium light spin set up with 6 or 8 lb line. There are quite a few smaller largemouth / Kentucky bass in the river, but I've also caught them up to 4 lbs. There are some stripers in the river below that dam and some near the bridge, but I'd bet they thin out once you head downriver. Generally speaking, you want to downsize a bit compared to typical bass fishing on the lakes. 3 or 4 inch soft plastics instead of 5 inch, 2 or 3 inch minnow / jerk baits. I would definitely have some smaller creature baits in the green pumpkinseed colors, some rapala minnows in black/silver and black/gold, and some smaller cranks that don't run too deep.. This time of year is probably not a good topwater bite and you're probably better off with plastics, jigs with trailers, maybe a smaller spinner bait. If the weather happens to be warmer, you might get them in the shallow water on a minnow.
The water will be cold, so you gotta thinks safety. Have a plan for if you flip the canoe. You can't just walk over to the truck and turn on the heater - you're on your own. Have a Change of good clothes in a dry sack. Don't wear any cotton.
