Hi STARFYRE, welcome to AA.
Here is an article on SW
Quarantine that may help you.
About the skimmer and fancy lighting, do you want a Reef tank (with corals, etc.) or just a FOWLR
tank (no corals, just fish)? If you want a reef tank, I'd go with the skimmer and you will need stronger lighting. Skimmers are another thing that I think is neccesary on a reef tank. You'll see once you fire it up and realize how much gunk it pulls out. There are others who think you don't need one either.
Can I keep live rock in there without all the excess contraptions?
I don't really understand this question. Could you explain?
