Anyone got any experience with this... Printing some big images on lightweight paper. Is there a magic button in Photoshop that gets rid of any excess colour?

convert to profile, set the profile you want and done...printer should be able to tell you the profile he needs...
...and normally the printer wants to do this conversion by himself, as designers mess it up.

I have some experience with it. Newsprint in particular doesn't like more the 220% ink, so you need to use UCR when converting imagery from RGB to CMYK. The default output isn't always ideal, sometimes you end up with really low depth in the blacks. You can try to compensate for this yourself by pulling up your info pallet, placing a eyedropper sample location on the darkest point (alt click eyedropper?) and watching the CMYK values as you fiddle with curves or levels. your total should not exceed 220% and your ratio should be something like 100k, 60c, 35m, 25y, for a pretty neutral black. If it looks weird on-screen, it will probably look weird printed.
