You don't need it to beat the game and elite 4. But if you want the shell bell then you have to get the 4 Shoal shells and 4 Shoal salts all located inside the Shoal Cave.
Shoal salts are (in fact) found in Shoal Cave, but you have to wait for a low tide. This is where the clock feature kicks in. You have to go in between a certain time block (don't ask; If I knew what it was, I would post it, huh?) and instead of the water being pretty high up, you can explore downwards. The shoal salts are located in little off-colored mounds of dirt. They ARE there, just have to look properly. This is also an opprotune moment to catch snorunt (Only hint to get it: YOU NEED STRENGTH).
Hmm... do you mean Shell Bell? If so the effects of it are: Whenever the Pokemon holding it deals damage, it restores 1/8th of the damage dealt as HP. You can obtain it by giving the old man in shoal cave 4 Shoal Salts and 4 Shoal Shells.
You don't build the stairs, they appear as the tide goes in and out. Wait until another time of day and then they should appear. btw if you get 5 shoal shells and 5 shoal salts then the man will make you a shell bell.
