Last time I checked, Whispering Dawn worked with Steady/Guard interrupts just fine, but the other two skills didn't if someone in range was under 80%.
For the OP, I wrote a guide that is primarily about fairies. There are a lot of macros there. I also discuss my targeting macros in the end. As a fellow controller player, they may be helpful for you. The URL for the guide is in my signature.
As for other macros, I use several space saving macros to basically put multiple skills on the same button.
Swiftcast/Res
Energy Drain / Aetherflow
Heel / Place
I also have Rouse macro'd with Whispering Dawn.
As for seeing your cooldowns (like Selene's stuff if you have macros doing double duty), you can set a hotbar on the screen and put whatever you want on there to see the cooldowns. It is super nice.
