That I remember, there's a ledge with bolts is closer to the base of the route and a little further out on the East Face. I believe the bolts Mike pictures weren't there the last time I was. Then again, that was about 8 years ago...
Going down the southern chimney descents seems neither faster or slower than descending the route with two ropes (I've done both). The traverse under the east face back to the base to get our packs went pretty quickly.
Spotly's "north side chimney" might be refering to the right hand option of the first pitch (?).
