I would personally suggest that you collect typefaces as you go along with different projects. I believe it's, in general, better practice to search for typefaces depending on your project style rather than sifting through a font collection in your computer that you are unfamiliar with. It's a common issue I've seen (while lurking) in the AC where good work is tainted by bad typography. More specifically, bad typeface choice. It would help you immensely to get more familiarized with typefaces and their properties before using them on your work rather than downloading a giant collection of typefaces that may or may not be of use to you or your style. Don't get me wrong now; I'm not directing this at you personally, this just happens to be your thread, lol.

In any case, I've acquired many of my (good) typefaces through other designers or have been purchased and I don't have permission to share them. The ones that are free I've gotten from DeviantArt (barf) in the type section or dafont.com. Good luck on your search. 
Well, about the typography, not only the wrong choice of the typeface can kill the design.
If you choose really good typeface for a design, which totally fits with it, you should also keep your attention on the color/size/style etc. Also, using the design fonts isn't that smart, if you choose to use one, you will have to think about that, to who is the design directed, the audience.
Blah, nvm.
Typography is pretty interesting actually, as I can tell.
