Here is my exact macros for my priest... you will have to tweak for your shaman.

Obviously my main is my focus. Change the <Name of Character #> to the names of your followers.

Modifiers such as Alt and Ctrl are split into Left and Right modifiers so that if I hit the left alt and the F1 key I get an abolish disease on my main, but if I hit the right alt and F1 I get a Powerword Fortitude placed on my main.

So the left mods are all things I will need while in battle and the right mods are all things I use out of battle. This is for easy of use during fights.

Obviously, each one of these is a seperate macro.
