Re: sea cucumber #2
Sea cucumbers are holothurian echinoderms, so are related to starfish and sea urchins. They are detrivores and feed in one of two ways. Some use their tenticles to filter the water column. Others burrow through the substrate and ingest particles from it, so if it's one of these then it should sift your sand well.
They have a tough skin so should be safe with most fish. As a defense mechanism they can eject their digestive tract, leaving a predator to feast on it, while crawling away to regrow it . Some can also eject sticky threads from their back end called cuverian tubules which wrap around predators, incapacitating them.

Re: sea cucumber #3
Some can do an excellent job of sifting the sand in established set up's. If you've a trusted LFS who have identified them as OK then no problem but more of a worry if they are not ID'd.

By your description and the fact that it's on the rocks a lot it sounds like it could be Synapta Maculata which do grow rather large, up to 24" I believe.

Re: sea cucumber #5
24" stretched out thank god mind you that's long........

It will sift the sand however there are smaller cukes better suited I believe. The other thing is to make sure your rockwork is stable as they can dislodge it whilst spending time moving amongst it.
