Print work - where to start

I’ve been asked to do some work for print, but I’ve only ever done web-based design/animation before. Other than the fact I should be using a CMYK instead of RGB palette I wouldn’t have a clue what the differences or things I should watch out for are! E.g. setting page gutters for the printers, etc. etc. Can anyone point me in the direction of any good places to start out?
I’ll admit I haven’t searched the forum yet (naughty wolfboy!!) so will do that now, but would be very grateful for any advice/links.

THANKS
