I can only answer the question about your DoT's not stacking with a friend's.
Assuming for the moment that you're playing a shaman and your friend is a necromancer, both of you get DoT spells but they belong to individual families. Shaman get Disease and Poison based DoT's. Necromancers do as well, plus other lines that include heat, health drain, etc.
If a target has a poison & disease Dot on it, and you go to put both of yours on, it will check to see which if the spells is superior to the other. Only the best of a current DoT family line will run, even if they are different levels / spell names.
Edit - attack haste, groundspeed movement, and damage shields are worth putting on pets. I think strength / stamina / dex / agility do a whole lot of nothing for them.
