since you want a reef, and shrimp, i would skip the puffer. i would also skip the damsel personally. its one tang or the other, which in this case i would choose the yellow, which its pushing its limit in your size tank. absolutely not the idol, they have such a specific diet that it sadly wont last a few months let alone a year.
if i was starting a new tank, i would fill it about half way with RO water, add some salt and turn on atleast 1 powerhead and heater. i say about halfway because the sand and rock will displace some water. i would also get some RO water and salt in a tupperware going with a powerhead and heater ( to make up for the extra water you'll need to add ) wait 24 hours, test salinity with refractometer. if things are exceptable 1.020-025 range, turn off powerhead for time being, start alittle bit of my rockwork, id then add either 1 inch (and under) OR 4 - 6 inches of sand. 2 inches is bad. you will notice the tank turned cloudy, which may take waiting another 24 - 48 hours for it to settle enough to see how to finish aquascaping your rock. ( which some people do outside of their tank, esp if the rock is dry )
keep in mind mixing RO and salt in the display can only happen the first time setting up the tank, when NOTHING is in it.
