Hey Chris, don't take this the wrong way, you should try and fix this yourself for the experience.
Some might pick up nurbs modeling very quickly, but it takes longer and more experience to know why something isn't working and the best strategy to fix it. Micheal has already pin pointed a lot of areas so you have a good head start.
It will make things easier and quicker in the long run, if you get stuck the forum is always here to help :)

Cheers and good luck.
