Wait. If all you are doing is just connecting the data to the site again (ie. dumping in ALL original data), then you module id's will be the same as they were before. In other words:
If you are dumping in the data that has the module id's from that same sql file that had these same comments, then the id's should be the same. You shouldn't have to modify them unless you activated the modules through the admin system panel, and then started dumping in the comments data.
