I'd go with Tubus racks - definitely stronger than Blackburn. I like drops and run them on my MTB-based touring frame - it's nice to be able to get a bit lower when bashing into the wind, but the main point is the choice of hand positions to prevent sore hands/wrists. As a second choice I would go with On-One Mary bars.
Personally I also use Magura rim brakes (I have the rare HS77 drop levers), or a mix of Magura on the front and V on the back. In the unlikely event of a failed Magura, you could transfer the V to the front.
For gear shifters I use the simplest possible: thumbshifters or bar-ends.
