No, if you block someone on Facebook, they can not see any of your activities
To remove someone from your Facebook you unfriend them and if that doesn't work you can block them. That will take them off.
You could try Account / Privacy Settings / Block Lists and add the person's name in the block users box. The help text for this facility says: Once you block someone, that person can no longer be your friend on Facebook or interact with you (except within applications and games you both use).
You can't do that, it won't let you do it
You can stop someone by sending message only by blocking that person from your Facebook. Messages will only be stopped when you block the person who is stalking.
Change the password on your account, then they will no longer be able to access your account from the old machine as it will still have the old password recorded.
