Hi spud , yes this is for triples. I don't know the answer to your bb question , the way it works is that it is fitted onto the bb cup on the drive side and held in place with the bb lock ring.So you need about 5 mm of cup protruding on the drive side , but that is how they work.

sorry I should have said, the hollowtech 2 has external bearings ( I hsve no experience with these) but I see no reason it should not work ,the mounting plate should slot onto the drive side bearing threaded section andthen tighten down to the frame. I would check with shimano, ring madison , they would know the answer.
