STILL Stuck in a treestand....
I am getting ready to take a Microsoft exam within the next week and in the process of studying I found a book I think will help you in your process to get your certifications. It's the Passport series by Mike Meyers and it's put out by Osborne. They have one for every cert. that Microsoft has. I have found reading this along with the testkings just about guarantees you'll pass provided you study. This does not compensate for hands on which everyone needs but it will help you pass. You can find the books in just about every bookstore.
