Some related tips:
In photoshop when converting just look at each of the channels for CMYK, to be sure there are no surprises before going to press. Also I've been told if you convert RGB to LAB then to CMYK it converts your blues a bit more accurately. I haven't noticed too much of a difference.For more control in photoshop go to edit > color settings and in "working spaces" change CMYK setting to custom. You can set your ink limits there, so that your rich blacks can add up to 300% or 250% (or whatever your printer will allow, usually not over 300).
In illustrator if you have a lot of flat color, make any main colors (like black) a swatch in your palette, and assign that swatch to all black elements. Then when you convert RGB to CMYK, just check that the swatch converted to the black you want rather than checking every element.
