Are there any spells that add to initiative?

[Crothian]

But he already rolled the initiative. It doesn't get re figured each and ever round. It doesn't matter if one's dex changes after it has been rolled.

That refers to Readying and Delaying, RM.

You can never go faster than once ever six seconds. That's how rounds are built. Even if the Fighter was already in combat when the Wizard cast Cat's Grace on him, it doesn't make him suddenly go faster than once every six seconds.

 

[dcollins]

(unless a character takes an action that results in his or her initiative changing; see Special Initiative Actions)

As the prior poster said, what's under "Special Initiative Actions" in the PHB are: Delay, Ready, and Refocus (last one in 3.0).

Haste increases init by 1, too

No it doesn't. Even if it did, you'd have to cast it before Initiative was rolled, so you'd have to guess that a fight is going to begin in the next round per level or it'd be wasted.
