Be sure to check out Twilight of the Idols by Nietzsche sometime soon. It's fairly short and was basically intended by Nietzsche to be an introduction to his stuff if I recall correctly. Although it's a short book, it really covers a lot of ground, and though I've only read Beyond Good and Evil and Antichrist alongside this work, so far it's my favorite one. I'm hoping to start Genealogy here soon.
I've been reading a bit of Schopenhauer here lately myself. I was able to get both volumes of The World as Will and Representation for fairly cheap, and so far I've been reading a lot out of the second volume. I'm less concerned with the metaphysics at this point than I am with his talk of life-affirming and life-denying religions, the idea of the Will to Live, and many of his descriptions of Nature throughout, which he basically describes as eternal struggle and suffering. For the book as a whole though, it's one of those I'll probably have to read more before I can truly come back and understand all of it. Hitler was a big Schopenhauer fan, but he rejected his pessimism.
