Gothmogs and dragons and noobs, oh my

[ninja91]

I will throw this thread here, because they are noob questions.
1. Gothmog is the lieutenant of the Morgul-Host. He is pretty powerful. But what in the heck is he? I cant find anything that describes him in the books. I doubt he is an orc. And even in the movies, he is different from the rest of the orcs, because they knew that Gothmog was somehow different than the other soldiers of Minas Morgul.

2. One more, where in the heck did the dragons come from? Where they created by good or evil, and either way, what was their purpose?

Thanks for the time,
