most of the all in 1 tank kits are ok, but you will more than likely be happier buying the exact components you want. as for cycling, pick a direction. there are people that will go ape nuts if you dont cycle your tank the way they do. in the end, they all work. some faster than others, and some with more stress on you, but it is a personal decision as they will all get you to the same place. as for adding fish, it is a good idea to spread out the addition of new fish, this allows your bacteria in the tank ( this is what the "cycle" is all about) to adjust gradually to the new bio load vs just making a huge adjustment if you dump a pile of fish in at once. good luck, and dont hesitate to ask questions as the need arises. tons of knowledge available here, and there is no one right way to do things.
