No, fsck does not check for bad blocks automatically (checking every 
block takes a long time).  You ask it to by:

e2fsck -c [other options] device

where device is the device file for your partition.

Do you need to reboot to run fsck?  No.  Do you need to run it on an 
unmounted or read-only partition?  Possibly, but it probably doesn't 
matter if you aren't fixing anything.
