Last I checked there are some holes in your facts/completeness. I may have missed something in the last build of the beta, but...
Base damage reduction is 8% from stance, Blade Barrier stacks ~multiplicatively, so it is a total of 13.52% reduction when it is up
IBF has a 2 min CD (120 sec)
Death Pact has a 2 min CD but Raise Dead has a 3 min CD, so a tank cannot use it more than once every 3 min
Army of the Dead's channel (duration of the damage reduction) lasts 6 sec
Glyphed Rune Tap only heals your party, to be clear, not an entire raid
Vamp Blood lasts 10 sec
Dark Simulacrum does not negate the cast, it only duplicates the spell for the DK
Guardian of Ancient Kings (will) has a 2 min CD (120 sec)
Divine Protection is a 20% magic dmg reduction when glyphed
Lay on Hands is a 10 min base (600 sec) and can be glyphed down to a 7 min CD
Survival Instincts (will) has a 2 min CD (120 sec)
Barkskin is 12 sec duration
Frenzied Regen heals up to 3% health per second, but consumes Rage to do it (0.3% health per point of rage consumed)
Shield Wall (will be) 50% reduction every 2 min (w/ talents) -or- 60% reduction every 3 min with the glyph
Enraged Regen heals you for 30% of your max health over 10 sec (wording above is unclear, it does not increase your max health)
You include some passive abilities like WotN, but exclude others like Holy Shield. You include some self heals like Rune Tap and Word of Glory but exclude others like Death Strike which will be a big effect and interacts heavily with DK mastery.
You've omitted a lot of resource costs. DRW for DKs is rather expensive (60 RP), as is Bone Shield (1 Unholy rune) and Army of the Dead (1 of each rune). Spell Reflect has a rage cost (15 rage) but can give you back 4 times that if it is glyphed and succeeds.
