Coilovers replace the strut, spring and shocks, and are usually height/damper adjustable.
Springs are just that - springs. You usually replace the shock as well if you have lowing springs, because OEM shocks aren't made for it.
You don't HAVE to replace the shocks, but they will blow much quicker if you don't.
