Export your document to latex, then run pdflatex/bibtex/pdflatex on this document and search for the deprecated commands in the .tex and .bbl file. If they are in the .bbl file then your problem is an old bibtex stylefile (.bst). If they are in the .tex file then your document itself or one of the used packages must have these commands defined.
Herbert, Thanks for the detailed explanation. I've got my work cut out for me as pdflatex fails with an error: ! LaTeX Error: Command \chead already defined. Or name \end... illegal, see p.192 of the manual. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.1551 ...nel@ifstar {\@dblarg\@@@chead}{\@chead}} % ? I'll look in my copy of 'The LaTeX Companion, 2nd Ed.' and see if I can find that error.
