Not a big investment for becoming a raid healer.
For movement keys, don't bind (Q)W(E)ASD as is default. Move it at least one key to the right, the further the better. That way you have access to more keybinds. => Using W for forward your little finger has no access to keys on the keyboard. Using E for forward, Q and A are now free to keybind spells on, with no loss of space towards the right.
EDIT:
Why the hell are mouseovers bad?
