I'm a big fan of David Pogue's "missing Manual" books. He has an iphoto book (it's only up to version 4, of course). As for ical, I'm not sure how much "missing stuff" there really is, but I know he discusses ical and some of the other aps in "OSX: The Missing Manual." That's been out for quite some time -- maybe you can find it at the library. As I said, I'm not sure exactly what's hidden in ical -- it seems fairly straightfoward to me. Iphoto is a different matter all together.
