how exactly can we help? My GF is fluent in mandarin (shes from Taiwan) Im struggling my way through rosetta stone myself.
Cool! My wife is from Taiwan. Tainan to be exact. Good Luck with Chinese. I have been with my lady for over 7 years and my grasp of Chinese is still very sad. I am now resolving to learning Mandarin along side the baby. Unfortunately, that means I am learning sentences like "I love mommy" and "I suck my toes".
At least I know Chinese for Cuba Gooding Jr is "Shao Gu Bao Gu Din". That's worth something, right?

well hows this sound, send me some wavs/MP3s of you speaking, and I'll see if my GF can understand. I can make some of her speaking as well. Out of curiosity, where do you live?
You can send the a copy to me as well if you want. My wife could offer a second opinion, my wife is pretty damn critical though. Also, it might helpful to put what you are saying in English along side it. A few screwed up inflections and she might think you are trying to say something completely different.
