I didn't know Scan Tailor, I'll have a look.

You should've just saved that ClearScan as images (e.g. with Acrobat, five minutes for average book I guess).
That way you'll get original scans, to run OCR on them again.
For Scan Tailor it's the best to use several double page scans for some practice beforehand.
It's fairly easy though, even for novices, we just have to get through those six steps, usually just selecting "apply to all" at each step (for an average text book there) when we are satisfied with the outcome on one page.
1. Fix Orientation
2. Split Pages
3. Deskew
4. Select Content
5. Margins
6. Output (for djvu files they recommend 600 dpi output but for pdf it's usually good enough to stay at original 300, that way it'll be also a lot faster than upscaling it to 600)
