Correct, it is the LSAT. As far as I know, there is no easy street to a law degree in the US. It is a very lucrative system for the universities, and will long remain that way if they have any power to make it remain so.
In what you say - it is a 2/3 year masters. There is no required pre-requisite on undergraduate study. It is foundation to being at the level to work (or be a sub-serviant lackey in a major law firm). Scholarships will be merit based - similar to business schools, above average scores for the school and applying as early as possible may enhance your chances. Not sure how common scholarships are for those legal eagles though.
