Shaman is a priest class. There is never a reason from level 1 to 60 for you to ever wear a haste item unless it has stats(end game raid gear).
Haste/items apply to the shaman's pet the same way it applies to all other pets. Note you can't get items back from your shm pet.
I know i'll get flack from people but what I'm saying is the truth. You're playing the wrong class if you're using haste gear on your shaman. Especially SCHW.

INB4 but baler haste gear on shaman durr Hurr bleh durrrrr
*shaking my head real hard*
Probably the same people who play ogre and can't grasp the concept that they're not the best race.

After level 14 a shaman should never be melee attacking.
(Root & DoT)
later levels,.. Root, Slow, Pet Attack, Dot, Meditate
50+ Root, Dot, Meditate
58-60 Root, Dot, Slow, Meditate
(Duo with a class that can actually melee and stop looking like a chump.) Monk + Shm duo is great
The only real viable melee weapon choices in order of accessibility...
Granite Face Grinder
Rune Etched Icewurm Fang
Epic
I maybe be mistaken but I believe the icewurm fang is the best dps out of the three. But you'll still be a poser for actively pursuing melee as a priest class.
*waits for someone to claim their druid melee is fantastic*
