What kind of action (standard, full round, free) is the Dread necromancer's negative energy burst. it doesn't say in the text.

Edit: also how long does her fear aura last. as in how long are they shaken?

Actions that do not state activation time are standard actions, as far as I know.

More specifically, supernatural abilities are always a standard action to activate, unless noted otherwise.
