Nothing to be nervous about. Just put one hammer head on one side and tap on the rounded side with the other until it straightens out. Promise your not going to hurt it worse than it is. Do the same on those other spots where it hit. Then if you have any burrs just use a file to clean them up. It probably won't hurt the performance enough that you would ever notice it but it could put it out of balance just enough that over a period of time it could damage a bearing but I'm talking lots of hr's.
