I feel that this book isn't too dense. Would love to hear your thoughts on this.

Thanks again.

That page should be fine at 600 dpi. You might have to clean it up with a denoising filter to remove the specks away from the text. I know that the open source OCR program "tesseract" would have a problem with those specks. Perhaps the commercial OCR programs aren't as badly affected by noise. If you do denoise the pages, be careful that the accents aren't removed, as well.
