Formatting can mean either removing everything from a memory device or changing the format of the memory device to something else (ie Fat32 to NTFS), which usually requires all of the data on the device to be removed.
Defragmenting is going through the device and fixing pieces where a mistake could have been made while writing the data to the device (fragments).
I wouldn't think defragmenting the SD card would damage it, but I've never looked into it so don't take my word for it.
