All of your RGB images will have to be converted to either grayscale (for 1-color printing) or CMYK (for 4-color process printing). RGB mode is not suitable for print and is only used if the final image is meant to display on some sort of video screen (like web graphics).
Without going into too much detail about color theory, a CMYK (or 4-color black) will give you a much richer black and white print than a grayscale (or 1-color black) image, but the production costs associated are much more expensive. That is if your printer is printing them using traditional offset.
Talk to the printer and ask them what they'd recommend. If they are running the prints digitally, they may prefer to have them in CMYK.

Be aware that in addition to being more expensive to print CMYK, that you might have trouble keeping the tones consistent across all the pics. That is: some pics might have a slightly greenish look, while others will have a slightly pinkish look.
I'd advise if you are not already very confident with that kind of thing, then stick with grayscale mode.
You could also do a duotone for each photo and get a 'sepia' look or add a certain color for a richer black and white effect.

Hello:
Considering it is a coffee table book I would think your choices are limited to CMYK or duotones. CMYK will give you the richer look but the casts colors(greens, pinks, etc) of the pictures could be a potential problem.
This can be overcome by looking at your screen %’s that make up the black and making sure they are all consistent. Just make sure they don’t exceed a total % of more than 280% when you add all 4 together.
That is a no-no in commercial printing. Printing it CMYK will definitely be more expensive and color more difficult to maintain. Duotones would be your other choice and a skilled designer can usually do a very good job.
Good Luck!
