Runes, pages, and words

[FizzleFinger]

Hello everyone,
So I'm working on my first toon on the server (42 druid) and I've been hoarding different spell components. I spent a good deal of time looking them all up, trying to see if they have any use, but my question is; Is there a list anywhere of the rare/valuable/never vendor runes, words, etc? Google has yet to find any kind of post about it, so I'm thinking just vendor it all and enjoy the bag space?
