What are the main beliefs or Zoroastrianism?

"Good thoughts, good words, good deeds."
and the fight between the forces and good and evil...
Is that all, or am I missing something?

Zoroastrianism- The religious system founded by Zoroaster and set forth in the Avesta, teaching the worship of Ahura Mazda in the context of a universal struggle between the forces of light and of darkness.

this is a good website to find info on Zoroastrianism

Zoroaster was the founder of the religion,he is comparable to Abraham in many respect.
Zoroastrianism adheres to a code of ethics similar to that of the ten commandments, and is thought to be the "father" of all monotheistic middle eastern religions. (doesn't mean that I agree with it!)
