I have used web courses and official study guides for preparing for the exams. Answering to the example questions is really valuable for me. It is also quit important to find author who is suitable for your learning style. My personal preference is Mike Chapple. And of course do not forget years long experience in the IT industry.
I was fortunate in that I have access to Books 24x7 which had a number of great titles available. I selected two books, the official guide and a second who's writing style clicked with me. Always go with the official guide, but have a backup because sometimes a writer just doesn't click with you on a particular topic. You should get a feel for the author thumbing through it at Barns and Noble. I also had access to a great video series on FedVTE through work, though there are plenty of other quality video sets available to buy and free on YouTube. If you want videos, again find a set that clicks with you.
What I did was hammer one domain at a time until I felt confident I mastered it. Read the corresponding chapter from one book, then the videos, then the chapter from the second book. At the end of each reading I would do the practice questions. After all the reading and videos, I went through another book that was just practice questions a couple times just to build up stamina on answering hundreds of questions over several hours. You'll also identify any weaknesses in your knowledge doing this. I also heard a lot of good things about the big question bank on www.cybrary.it, though I didn't personally use that.
I used a virtual training environment to review all of the material. I spent quite a bit of time on the cccure.org site using their quiz engine. I also used the Shon Harris book and accompanying CD for more questions. Once I felt good with my comprehension of the material, I attended a boot camp that coincided with my scheduled test. It seemed like overkill at the time but I did pass on my first attempt.
I hope this is helpful.
