If there aren't any plants where you're casting, you might want to set the bait at the bottom as a bases to find where the catfish are feeding. I actually only used one method for cat fishing so far, so I can't give you a myriad of information on different set-ups. I always used a 6-8 lb test of mono tied to a barrel or snap swivel; a #6 shelled hook attached to the other end of the swivel, and an appropriate sized split shot above the swivel on my main line. I always used live worms. Livers and hot dogs also work well. I'm not sure the rules regulating your state, but in Jersey, we're allowed to have up to three active rods at a time. With cat fishing, it may be a good idea to have more than one active rod to increase your chances, but if it is an extremely active day of fishing, you'll find that it can be overwhelming trying to set the hook (If you aren't using circle hooks, in which case, the fish will almost always hook themselves), and reeling them in. As for the float, I never used one when targeting catfish, but I heard of it being done with success on the last forum I made on cat fishing. I've received some great tips on it if you want to check it out.
