It's a good idea to review concepts like limits, continuity, sequences, and series. For basic real analysis this will be more important than the various techniques for calculating integrals and derivatives, which make up the bulk of most calculus courses. Also, multivariable calculus is not a prerequisite for elementary real analysis.
Getting your hands on a theoretical calculus book such as Spivak's or Apostol's might be the most productive way to "review" calculus if your goal is to study real analysis. Indeed these books are gentle introductions to real analysis as much as they are calculus books.
