Rockauto has a bleeder screw kits for calipers so I'll buy them next time I want something from RA. Hopefully I don't break them off, but if I do, an EasyOut should fix that problem. I soaked them with PB Blaster.
I still think the vibration after heating up going down downhill is because the rotors are getting thinner from wear, and the heat buildup causes the warping - but who knows. I understand the argument for incorrect bedding-in and uneven pad material on the rotors, but don't really buy it because that would suggest that the rotors would warp shortly after initial installation during a heat up cycle and they were fine for many many miles and got worse over time (rotors getting thinner). Now though, I replace the rotors each time I change the pads because of all the rust that seems to grow on the rotors which cause funny uneven pad wear. Hopefully the coated rotors last longer and don't rust as much. The new pads and rotors sure feel nice now and no vibration either - so I must have bedded them in correctly! Will see after 60K miles.
