Dear N.F.T,
I do not prepare for TOEFL, I prepare for IELTS, but I am a coordinator of online English school in Russia, so I know quite a lot of useful resources for our teachers and students. Here are some of them. Hope It will help.
Of course, you should also have some MODERN TOEFL coursebooks , the more the better ;).
