I am sorry but, I have not fished the area you are asking about. But it shouldn't fish much if any different than most other rivers.
Deep holes, especially if it has some brush or log jam, is a great place to start with the rod and reel or limb lines. If you want some big cats, I would put some perch in the 6-8 inch range on those lines. Don't foget to set some of those lines along some of the shallows and tailend of riffles. When the lights go down, the cats will prowl. I have got them in water shallow enough that their backs were out of the water.
If you can seine some shiners, worm them on to your limb line hook. Channel cats are not picky as to if it is alive on not. Flatheads are.
For your rod, and since you only have this weekend, I would just go to the bait shop and get a jug of some brand of catfish dough bait. I like the blood flavors. Though I must admit I haven't bought any since they quit making bloodbait. Anyway just roll a small ball of it on your hook and toss into those brush piles. That should keep you plenty busy. I used to do that years ago and it was nothing to catch 20, 30, or so channel cats. Nothing huge by any means, but up to a couple of pounds at times.
Most importantly, if you set some lines...take them out when you are done. I hate nothing more than seeing old limb lines hanging everywhere with bare hooks.
