Most of my replacement bolts were pre-applied with loc-tite. I would put a dab of the blue loc-tite on each bolt just to be safe.

I'm not quite sure about the torque specs on the control arms, however, you must technically leave all of these links loose enough so that they settle correctly when the car is let off the jacks, then you must tightened them while the car supports itself. The control arm bolts will just be loosened/tightened again properly when you go for an alignment anyhow.

Also, those 12 pointers go by the name of spline bits or XZN bits.
