I took the TOEFL a second time a couple of weeks ago, and I got 118! Reading: 30, Listening: 30, Speaking: 30, Writing: 28. Of course, I'm very happy with this score and I'm glad this is out of the way. In the end, I didn't practice the writing section a lot more than the first time. I just tried to memorize the essay structure given as an example in the official ETS preparation book. One more thing: don't be afraid to retake the TOEFL if you think you can do better, unlike the GMAT it is possible to choose which score you want to send to the business schools you're applying to.
Good luck to all of you!
Now the real fun begins, it's time to start studying for the GMAT...
I am about to take the TOEFL in a month time now, I read your post and was surprised by the fact that you can actually choose the score you want to send!. Is that the case for any school? Say you got 90 and then 115, schools will not be able to see your first score?
