I realize that it has been quite some time since you posted this, but I've been busy and I thought someone else would reply quickly.

The obvious choice in your situation is to take the CBT any way you can.
This is my reasoning: whenever a test format changes, test-prep instructors and test-prep material writers are forced to guess what is on the test. It takes time before these guesses become actual teaching techniques that work well.
There is plenty of good material out there on the CBT. Specifically, I would recommend getting your hands on the old PBT test books (sold by ETS) as well as their Test Preparation Kit. Follow up that preparation with going over the POWERPREP software that you can download for free from www.toelf.org.
If you feel you need much more help, I would recommend using TOEFL Success , by Bruce Rogers. He has another, newer book out, The Complete Guide to the TOEFL , but I haven't used it and am not able to comment on its quality.
I would spend a great deal of time looking up vocabulary words and idioms in the actual TOEFL Practice Tests. Generally speaking, vocabulary books for the TOEFL are not worth the paper they're printed on. If you feel that you really HAVE to build up your vocabulary for this test, however, I would reluctantly recommend Milada Broukal's Vocabulary for the TOEFL Test , fourth edition.
Not much information is really being spread by ETS about the new iBT. Excellent hype, but little substantial data. This, of course, is because test-prep instructors got uncomfortably good at preparing students for the TOEFL Paper-Based Test and the only-slightly-modified CBT. We could take students who could barely speak and write English and get them to pass with minimal effort. However, many of these successful candidates could barely function in real academic settings.

This inspired the University of Cambridge and IELTS Australia to work on creating a new test for academic English, the IELTS, which gained rapid acceptance for its credible results in the UK and the rest of the world. More and more British postgraduate degree courses are abandoning their TOEFL acceptance policies now that they can rely on IELTS.

Since the iBT has been created to combat the problem that test-prep books and teachers can successfully get you to pass the CBT without really knowing English, it stands to reason that you, as a foreign student who cares more about achieving a cut score on an acceptable test in a limited amount of time (and not delving into the mysteries of the language at your leisure), should take the TOEFL CBT.

Best of luck.
