as tank (athanati) i use this spec http://www.wowhead.com/?talent=j0xMZGxxtGc0ohRVssxcg
this is a frost 2h spec since unholy nerfed i think this is the best spec for now if u use 1h weapons i suggest http://www.wowhead.com/?talent=j0xZGxetuc0ohRVssxcg
Glyphs u must have as frost tank r : Glyph of Icebound Fortitude, Glyph of Unbreakable Armor (both major)
before patch i used this unholy spec with 1h weapons http://www.wowhead.com/?talent=j0xZGx0zZcg0hxcoxeMocsut which could be still very good if u dont have good gear yet
Glyphs u must have as unholy tank r :Glyph of Icebound Fortitude, Glyph of Bone Shield (both major)
a good addon for watching your runes cd's is DeathKnight.info Runes
as for minor glyphs : Glyph of Horn of Winter, Glyph of Raise Dead
