This thread is long dead, but I just picked up the book Mother of Purl, which contains the so-called pattern for the Lost in Translation scarf. The yarn she specifies is Rowan Kid Classic, and the pattern looks a bit different to me, but that could just be the difference in lighting between the film and the photo in the book.
I found the instructions in the first Stitch n Bitch book quite helpful. You might want to start with a basic worsted weight yarn (I quite like the Lamb's Pride Worsted) and a needle like a US8. My first project was a ribbed scarf. It really got those knits and purls drilled into my brain. Good luck and have fun!
