I don't think so. It's about ten years since the ILI established TOEFL preparation courses.
Probably in other towns it's a new course. If you are coming to Tehran, you can buy those books from every branch of ILI.
But I suggest that you go to central department and buy them from main book store.
You can find the central department in the following address.
خ شهید استاد مطهری - خ جم - ساختمان کانون زبان ایران
Just make sure that you buy Structure,Reading and Vocabulary books for PT1. The listening books are useless because you can't get the tapes.
In addition I have to tell you that when I took the exam there was no speaking test. Just 20 questions of listening. 20 questions of grammer, 20 questions of vocabulary and 10 questions of reading comprehension.
Be sure that you will pass the exam. If you get 250 from 640 points you will be able to attend PT1 classes.
