Has the bike been sitting all winter?
It's normal for the pads to drag just a teeny tiny bit on the disc.
If the bike has been sitting for a while perhaps the pads are not retracting as far as they "should"?
Ride the bike. Have fun. Put some good miles on her.
Then check again.
In other words...I don't think I'd be overly worried at this point.
It's possible they calipers need a little lubrication, but it's also possible it's just from sitting all winter and the noise will go away once you've worked the brakes under a real load for a few dozen miles.
