You should really check out the WAMAS forum. Lots of good info and helpful people over there.
I recently set up my first saltwater tank and from all my research and conversations with more experienced people, smaller tanks are a lot more difficult to stabilize and care for. Also anemones need a very well established tank (running/cycled 6+ months).
Not trying to discourage you or anything but keep in mind that you have to have a lot of patience and time for a saltwater tank. I spend a lot more effort on my sw tank than any of my fw, but I do think it is worth it.
