you are prob not going to heed this but I strongly suggest against buying any expensive corals now.
Just go for mushrooms and zoas 1st in other LFS 1st. They are more hardy and less demanding.
GO corals are not cheap. (not that you cannot afford it of course). No point spending hundreds when you are not sure of your tank condition.
pick up more experience 1st.
For fishes, go for more hardy fishes and smaller ones if you can.
Just have about 5 - 6 fishes 1st and try to hold them healthy.
remember to be diligent with water changes and dose bacteria to assist.
When you feed, try to feed in a particular position everytime.
Train the fishes to know where is the feeding station. So that you do not end up flooding food in the tank.
