Sounds like you've made serious headway into the genre, OP. I think you're probably at a point that you can draw the sub-genres out of Fantasy and pursue ones that you prefer. Here's how I see them, but I'm no expert.
If a standard fantasy novel is "a novel of a journey that includes magic or mythical creatures," then...
1. Dark Fantasy - would take place in a mythical world that resembles our antiquity to dark ages. The themes are often darker and the settings often more grim, with war a central theme in many of them. Examples include Tolkien's Lord of the Rings, Martin's A Song of Ice and Fire, and Sara Douglass' Wayfarer Redemption.
2. High Fantasy - takes place in a world that resembles our period just past the dark ages to our Renaissance. Kings, Queens, Jesters, Castles, the whole bit. Most fantasy is this sort. Examples include Robert Jordan's Wheel of Time and David Edding's Belgariad. Robin Hobb and Tad Williams are also worth checking out.
3. Adolescent Fantasy - probably a subset of High Fantasy and sometimes includes Accidental Fantasy, this is where we get stories about young kids losing their parents and learning that only they can save the world--with allegorical themes of maturation and acceptance of the world around you. Pretty standard RPG stuff, but some real gems in this sub-genre if you're looking. The obvious is Harry Potter, but also check out His Dark Materials by Phillip Pullman. Also, CS Lewis' The Chronicles of Narnia.
4. Dragon Fantasy - probably a subset of Dark Fantasy, but is obvious when you see it. These novels center around dragons and more dragons, and tend to focus on them as characters rather than beasts. I hate this style of fantasy, but Anne McCaffrey's Dragon Riders of Pern and the standard Mercedes Lackey stuff come to mind.
5. Accidental Fantasy - These are the ones that start off in an otherwise modern setting and end up in a magical, mythical world. Tad Williams wrote a fun novel called War of the Flowers which is an enjoyable, quick read. Harry Potter falls under here. If you want something closer to sci-fi, I definitely recommend Tad Williams' Otherland, which is probably my first or second favorite series ever.
6. Romantic Fantasy - This is high fantasy that typically focuses on two lovers as they journey through a turbulent, magical world. Terry Goodkind's Sword of Truth series is an example of this. If you find the right books, this subset is fine. The wrong ones though (Mercedes Lackey), and you'll find yourself not finishing the book.

From the ones you've mentioned, I highly recommend David Eddings entire catalogue. But start with Pawn of Prophecy. Well written, quickly moving, charming characters, with just enough wit to make you smile despite yourself. I can't speak highly enough about this series, The Belgariad (and its follow-up, The Mallorean). This is the series that you were asking for when you started this thread.
