I used this E&E in my first year, helped out a lot. Civil Procedure is pretty arcane and weird as far as 1L courses go -- there's not as much "common sense" stuff as you'll find in Criminal Law or Torts. On the other hand, that means you can approach it from a purely "I have to just learn these rules" perspective, which might work well for some students.
Either way, Glannon's E&E is highly spoken of for good reason. Go ahead and get it, though it's probably better not to attend law school at all. I wanted to be an astronaut when I was 10, and now I spend all day reading documents and managing cases. There isn't enough liquor in the world to help me -- good thing I quit drinking.
