I would use a rubber float stop if you can get one. That just stops on the line on the reel. I put a small loop in the end of the reel line. That can be threaded through the float and the lead. I then poke the loop through the eye of a swivel over the end and then pull back. Nice thing about this set up is that it can be easily done up and undone. To the swivel I would attach a 12ins hook length - or shorter if I had hook line tangle problems above the float.
On depth I would try 4ft for a while.
