Thanks for your help. I guess I'll stick with my current file and clean it as I can. I don't know much about regex tools, so I'll just do as ATDrake suggested:
- replace </b> <b class="calibre3"> with single space
- replace <p class="calibre2"><b class="calibre3"> with <p class="calibre"> (which is the "basic" class in the stylesheet)
- replace </b></p> with only </p>
- etc.
I'll also keep in mind the tip about commenting out the parts of the CSS file I don't understand and which doesn't seem to do anything useful. Merci!
I appreciate the fast and friendly help—great forum!

Update: Just spent some time cleaning the book as you suggested, and it looks scarier than it is. It's actually very easy to do and in a couple of minutes the file looks MUCH better. I guess I should have tried that "find & replace" thingy way earlier... Thanks again!
