I'm really considering the intensivist program at Vanderbilt as well. My fiance and I are planning to move to Nashville in the spring, but I'll need to get ICU experience first. So far I've worked a little over a year of cardiology and 6 months of ED. Being an intensivist just sounds like such a cool job to me. As far as the GRE goes, I got a Kaplan book for it and did well on the reading and quantitative reasoning sections. I under estimated the writing portion, though, or maybe even over estimated it. I was expecting to write about a logical topic. Instead, I had to write a paragraph on two separate topics including why a happy pancake house should use margarine instead of butter and another on why undergraduate students should take courses outside of their intended major. The second I could see, but I couldn't manage to show off my intelligence with the happy pancake house. I scored poorly in the writing section, which thoroughly surprised me, but I plan to retake it. Hope this helps at least a little!
