Hi & welcome to the forum, you'll find lots of helpful info on the SW threads, otherwise just ask if you're not sure about anything, there is usually somebody around to help.
I'd also take a look at the diaries, I know you can't get all the foods we can so that won't be easy, but if you look in Britmumincanada diary she'll have some foods you can find in the shops. But she has just changed from SW so it's the earlier foods, she also has a fb site with yummy recipes on.
