If your raid doesn't have the 10% buff then going demo is the best for the raid, even more so if it's 25 man. The percieved 'loss' going demo from either aff or *shudder* destro is now not a valid concern, unless you have nextt o no mastery on gear and reforged for haste or soemthing like that.
As for Doomguards, pop it when you have your orc racial (if orc), volcanic pot, any int/mastery procs up all at once, THEN pop it. The doomguard takes a snapshot of your stats when you summon it, so you want it to be as pimped up as possible. It will not benifit from lust/heroisim and haste that is not on your gear will not boost it's cast speed (moonkin aura/shammy totem and I think DI's haste, not sure about the damage buff, I doubt it though, not really looked into it.)
Hope this helped a little.
