Not sure about the first question, but you can remove all roles from a User Account to effectively disable it.
You can safely delete a user account, it will not remove anything that user account did.
I don't like deleting records either, what I do is restrict the IP they can login to as 127.0.0.0/8 and reset the password to something random and then remove all their groups but I created a group with no permission roles and named it Disabled User. That way if they would come back, I just remove those settings.
