If you have drained and refilled the tank a couple of times to remove any salt, then you should be fine to start cycling them again.
You don't normally have to replace any of the filter media unless it is carbon or some other chemical based filter media. Sponges, noodles, etc can simply be cleaned and re-used. However, if you have already replaced them it won't hurt anything other than your wallet
