raniskeet has a good point; if you've read and really understand the content of both of those, there's not too much that you'll learn from just reading more books. I'm pretty much in the same boat as you (read The Good Parts, started the Def Guide), and my next step is not to read about Javascript, but to read Javascript. Pick a codebase of something you use or want to start using and learn how it ticks.
Great start! Here are a few other books I've read recently and marked the crap out of because there is so much good information in them.
- JavaScript Patterns by Stoyan Stefanov
- High Performance JavaScript by Nicholas C. Zakas
- High Performance Web Sites by Steve Souders
- Even Faster Web Sites by Steve Souders
Here are a few I haven't read yet but are on my to read list.
- Object-Oriented JavaScript by Stoyan Stefanov
- Pro JavaScript Design Patterns by Dustin Diaz, Ross Harmes
