You need to let it cycle for a couple days just to be safe, but other than that you can start out slowly by purchasing hardier fish then upgrade to you more expensive fish and corals

Yes. When you first set up a aquarium you have to clean the equipment using just water and paper towels but that does not get off all the dust and manufacturing film. By adding water, sand/substrate, equipment, and then letting it run for a few weeks you not only cycle the tank but check for leaks and problems as a whole.
