You should definitely check out some books before jumping into corals. "The Conscientious Marine Aquarist" listed above is a good one for general aquarium info. If you want a great book for coral care check out "Aquarium Corals" by Eric Borneman, its loaded with great info. I also like "The Natural Reef Aquarium" by Tullock.
The corals biotoxin listed are good beginner corals but they are not sps
corals. They would be soft corals. Xenia can be difficult to keep for a beginner. I've had good luck with leather corals, mushrooms etc. Anemones are not very hardy, require good water conditions and very high light so I wouldn't recommend one to a beginner.
