Second, 500 pages of notes is insane. Your novel won't even be that long. Can you have a fear of writing the novel so you keep writing notes about it?
Even more importantly, is your keeping such detailed notes actually preventing you from writing the story itself.
Switch's first advice, "write what you know" is always a guiding principal in fiction, as the author's familiarity with a subject speaks much louder than extensive academic research (which always sound remote and overly format, and the 'in the trenches' remarks which makes readers feel a part of the story.
I also like Switch's 4-point list, though I simplify it a bit. I write the story description first, when I focus on the main conflicts in the story. Since it's a basic 1 or 2 paragaraph overview of the story, I ALWAYS refer to it as I'm writing, to keep the story focus on THOSE conflicts.
You can easily add secondary conflicts, but the secondary conflicts I've found the most positive are the intercharacter conflicts, so I'd list each characters' motivations. This helps, because during the slower discussion chapters, if you have two or more characters arguing what they encountered acutaly means, or how they should handle it, it really makes otherwise boring chapters much more intriguing.
Finally, with your current work, I suspect you've gone overboard with the research. Unless this is specifically a historical piece in a foreign language, I see little need for such detailed notes. I'd suggest you simply write the story, and whenever you hit something you're unsure about, either do the research then, or use this forum to ask if anyone has any particular knowledge of the field that you can draw on (asking for specific examples helps with the 'real-life' experiences in the story.
