No need for a "D" tool for the right cup, it's just 36 mm and you can use the 36 mm headset spanner just fine. The only thing I'd add to Kerrys list would be a Allen Key Multi tool like <a href="http://www.nashbar.com/profile.cfm?category=99&subcategory=1230&brand=&sku=2638&storetype=&estoreid=&pagename=">this</a href> one.
That kit has mostly shop level stuff. The cone wrenchs are great compared to the old stamped one, those are plasma cut Cro-Mo if I remember, although I wish it were heat treated tool steel myself. I'd get another set of them though if I were going to be doing a lot of work like on a neighbors or relatives bike regularly, you can never have enough 15 and 14 mm cone wrenches.
