For problem 9, does anyone know how to prove that dim null T = 1?

I don't think that the null space is necessarily of dimension 1.  A  
more fruitful approach to the problem is probably to think that many  
eigenvalues require many eigenvectors and that those eigenvectors are  
going to bulk up the range.
