From the description of the skills, I assume Cold Blooded, Slow Time, and Conflag all work for party members also, since they do not say YOUR damage is increased. The easy way to check would be to use your follower with a low dps weapon and some extra +min damage so he hits for the same amount. Then use each ability (frost nova w/cold blooded, slow time, and some fire skill) while trying not to do any damage so you can see the damage done by your follower.
Also, before it's asked, I assume the cold blooded and slow time buffs are multiplicative, so with each you'd do 44% more damage.
Regarding the hydra, personally I'd just try using Firewalkers instead of hydra.
