Facebook question about privacy and posting comments on another person's wall?

[.]

I want to add somebody as a friend on Facebook, but I have noticed that she has her settings on public viewing. I have my settings set as friends only, so if I add her as a friend, will all my activity and comments on her page, and my page be on public view? Also, I don't want one of her friends seeing all of my activity!

I'm relatively new to Facebook so I don't know the best thing to do!

Thanks!

Well people can see what you have posted on her wall or relating to her such as photo/comment tags but when they browse your profile it will be restricted.
