Facebook Privacy Help?

[A Woman]

Let's say I have deleted Person A off my Facebook but have NOT blocked them.

If I have my privacy settings set to 'friends only' for everything, will Person A be able to see messages left to me by mutual friends?

I say again, my privacy settings are 'friends only', and 'friends of friends' is NOT ticked anywhere in my settings.

Just want to check, thanks.
OK one more thing thank you...

How do I prevent my profile picture showing to non-friends?

No they won't be able to view it. It's purely friends.
