For reference, you can look at XenForo Media Gallery and XenForo Resource Manager installers to see some of the data that has to be manually removed. Permission entries and content type specific data are included in this.
The permissions should be removed automatically, which is odd, though, so there might be something else at play.
As a side note, I would probably avoid making structural changes to default XF tables (e.g. increasing the length of the data_key column in the xf_data_registry table).
