If you are going ot have live plants (a very good idea in any aquarium) plant them immediately before the fish go in, once the tank is filled, heater and filter working. Then add some fish. Plants require ammonium which they convert from ammonia, so they will act as the "cycle" agent. Move over filter and media as suggested previously, ensuring there are no snails; this will add the bacteria that will work with the plants in the cycling. I would not add any source of ammonia other than the fish. The zebra danios would be good fish to first move into the new tank. After a couple of days, move the rest of the fish. I would not bother using the old gravel; it won't be necessary and it risks transferring snails. Don't know whytype of snails you have, but the usual ones are good in most tanks, but that's your preference.
