[WOTLK] Which stats affect my Fire Elemental?

[Kayeto]

At the time the Fire Elemental is dropped, which, if any, of the following stats impact my fire ele's output:

Spellpower
crit rating
haste rating
% haste (such as from BL/Ele mastery/Troll berserking, PI)

If I have Totem of Wrath out when I cast Fire ele, does the +280spellpower go into the fire ele? Or was the totem of wrath already "gone" before the Fire elemental came out?

After the Fire Elemental has been dropped:

Does changing my character's stats affect what the fire ele will do? If Bloodlust is used then, will it benefit the fire ele?

As far as I know, only spellpower counts
