DK tanking gear while leveling up

approaching level 70 with my DK, with the new changes to tanking stats what stats should i be concerned with acquiring while questing/instancing? very poor *though have guildies happy to help with making stuff* want to be able to solo-quest and run instances as a tank

The level 70 Cobalt gear is still very nice - plenty of stamina and dodge. It shouldn't be too expensive, probably like 40-50 bars to make the whole set.
