Warlock Pet Questions

I am playing on WoW 3.3.5. I use the following fight class spell to cast "Consume Shadows". It casts fine, but because it's a pet channeled ability it is immediately cancelled because my character starts moving after casting. Is it possible to add some type of wait command after casting? Also, I have seen other places on the forum where people ask about waiting for your pet to have aggro before the fight class rotation begins. It seems "Combat start since ms" is the only answer, but do I need to add that condition to every spell in the rotation?

Thanks.
