I can set the pdf format using \setupbackend but I'm unsure as to what to do about CMYK workflow. The book has no colour pages so I'm not sure if I really need to worry about CMYK workflow. Could someone advise?

\setupcolors[rgb=no] to avoid rgb colors, or
\setupcolors[state=stop] to force black and white.

You must ensure yourself that your images are just black and white / greyscale (not in RGB mode).

ConTeXt does some automatical checks and conversions depending on the PDF/X standard, but I’m not sure how far that goes (e.g. PDF/X-1 prohibits transparencies, and ConTeXt cares for that).

Best, Hraban
