I had a 2008 CR-V, the parking brake is not hard to adjust. I might even still have a printout of the procedure at home. I think you can find the procedure through Autozone's online repair help too.
Jack up the rear wheels, take the wheels off, and pull the rubber plug out of the face of the rotor. Turn it to line up with the adjusting star. Tighten the adjusting star until it won't move, then back off 3 clicks. That's the coarse adjustment for the shoes, and that's all mine needed. The cable adjustment involved putting x number of clicks on the pedal, and tightening the cable adjuster until the wheels don't turn by hand.
Unless somebody went driving with the parking brake on, and ignored the furious beeping from the car warning the parking brake was on, I'm sure the shoes are fine.
Edit: Be careful putting the rubber plug back into the rotor, it's easy to push it through, and it's a pain to retrieve it.
