Can my contacts see my facebook updates if they are NOT one of my friends on facebook?

depends on your privacy settings
go to your account settings and check them to see how private your profile is

Check your privacy settings. If you allow something that's friends and network and say, for example, the network is New York City, then anyone in New York City could see your updates without having to be a friend of yours on Facebook.
