Hey welcome to the board!
I would say that a 30 could be considered a nano, but in all actuality its really just a label. THe principles are all still the same.
As for my tank, all the equipment that I use is listed in the very first post of this thread. I do not have a sump or a refugium and I never have. If I had the room, I would have a fuge though.
As for lightingm it really depends on what your goals are for your tank. What you want to keep in it and what not.
If you go to the new hobbiest forums, there is a weekly thread aimed at new hobbiests that covers the basics. I write it each week and its called "Saltwater Aquariums 101: (what ever topic is being covered)" The first week wes on setting up a tank, then last week was on some equipment. The next week is going to be on water sources, filtration and the cycle. After that I will cover lighting.
In the mean time a great place for you to start is to get a good book on aquariums. I recommend "Natural Reef Aquariums" by John Tullock. Awesome book with all the info you need to set up your first tank.
Again, welcome!
