[Lord of Angmar]

I think it's definetely Smee-gol because that's how they say it in the movie.

Yeah, but they also pronounced Eärendil, eh-ren-deel.

I assume by 'Numenore' you mean Númenórë, the Quenya name for Numenor. It was pronounced Noo-meh-noh-reh in Quenya (this is a rough pronunciation guide... there are subtle guidelines about how to pronounce vowels in Elvish which are too complicated to explain here). 'Numenor' is roughly pronounced Noo-men-oar.
