The same team [that recently reported Water Ice on the Comet's surface] previously reported that Tempel 1's interior also contained an abundance of organic material and suggested the comet may have originated in a region of the solar system now occupied by Uranus and Neptune.

What is the "Organic" material in the comet?

And is that material related to their suggestion that the comet originated near Uranus and Neptune, or is the origin point just incidental to the organic material.

Organic in this case is materials containing CHON (Carbon, Hydrogen, Oxygen and Nitrogen) this would include, but is not limited to, methane, ammonia, and water

Ok. So, nothing more complex than the basic organic elements?

That's pretty much the definition of organic when you apply it to this planet too. Organic, historically, was believed to be materials only produced by a 'life force', but the synthesis of urea in the 19th century pretty much out that definition by the wayside, Today organic means the chemistry of carbon
Particularly carbon/hydrogen bonding. This includes materials containing, but not limited to, three of four of the most common elements in the universe (CHON).

The contemporary meaning of 'Organic' as natural is scientifically meaningless.
