Heh, activating supernatural abilities is a standard action. It's a constant ability though, like the flames of a Balor (it doesn't have to activate those).
The truth is, if you look at Song & Silence and the PHB, you can hide while moving if you have something to hide in (shadows, in this case), but attacking reveals you, and you have to hide again. While sniping you can attack and hide again as a move equivalent action (a -20 penalty).
I'd say the same thing works with a Spring Attack. You can stay out of site while attacking if you succeed a Hide check with a -20 penalty for being rushed (and an additional -5 for moving).
