[BetterRed]

@Scarmandros - what I know about MOBI would fit on a Penny Black, but here's my tuppenceworth.

I would convert the DOCX to EPUB and see what it looks like externally via the calibre viewer and internally via the calibre editor. That would give me a clue as to whether the problems are in conversion or Word.

I'd also try exporting from Word to a PDF - books such as your friends are often better suited to a paged format, which is what a PDF is, rather than a flowed format like MOBI or EPUB. It might give you a 'benchmark' with respect to appearance.

Others who know better will happen by, but you could try those ideas whilst you're waiting and maybe get some clues to pass onto them.
