You'll probably run across the ones you'll need in books dedicated to the JLPT.
They show up all the time in novels, though, so it's worth learning some of them; it's a little easier on me to just pick them up as I go, though, since they're usually either incredibly obvious (一石二鳥), obvious after looking them up, or incredibly vague and based on some old tale.
Can't think of good examples for those latter categories at the moment, almost out of time.
