Hi, i am also planning to take early action for 07 MBA. Actually, I postpone my MBA application to this year for some personal reason. I did research for different US biz schools to see which is the best one for me. If you have the basic questions as mentioned above, you can go to each school web site first to get some flavor. After careful consideration, I remove MIT, NYU and Columbia from my application list because MIT is better for engineering majors, NYU and Columbia is better for pure finance guys. I may prepare for Wharton, Kellog, Ross, Chicago GSB, Yale SOM. If you are not busy, I suggest you can prepare for essays of general questions, such as Why MBA, Why now, Why me etc.
