You must have a duplicate site where you can practise this sort of experimentation without the stress, then you'll know as well as anyone how it works, much quicker than asking questions piece-meal.
As well install and use Dr Byte's Backup Mysql plugin on your duplicate site.
You can experiment and undo mistakes very quickly using this.
