Mastery is inferior to intellect over every fight length. According to a recent post on EJ, the PPM is about 1, mathing out to 321 mastery average buff, but also remember that random-proc buffs are generally worse than constant buffs or click-buffs for healers.
You still do have 2 hots that are affected by haste, so haste is improving your HPS as long as you have them running. Haste is also making your GCD faster for your instant casts, and reducing cast time on non-instants so that you can fit the more efficient but slower heals into shorter periods, improving both your HPS and mobility (as well as dramatically improving your performance on semi-mobile fights, of which there are several this tier).
Trust me, I know enough about holy. It's imperative to to know how other healers work once raiding.
