Countdown to CFA Level I

[spider]

Quick question about study materials: I have the official CFA study curricula (volumes 1 to 6) that say 2007 on the cover. Will I be able to use these for studying for the June 2008 test? I assume there will be updated 2008 guides but the vast majority of material I've seen in the 2007 books seems 3 to 4 years old.

And given that I have the offical stuff already, does the Schweser stuff add much?
