I've done the shock treatment occasionally for iron bacteria as well.
Something to realize, however - bleach will not penetrate sediment mats; you can keep a high bleach solution sitting in your pipes overnight, but if there's much sediment somewhere with bacteria in it (eg, bacterial mats), you won't kill it all. It's still a nice thought, though.
Re scented being poisonous vs unscented - I can't say if one's more poisonous than the other; my guess is that the chlorine is more poisonous by far than the scent.
After letting my well sit for a bit, I pump until a chlorine test kit (from a pool supply) doesn't show any color - after smelling chlorine for a while, I can no longer trust my nose to detect it in small amounts.
