You definitely need Leiningen for easy project management. There is a multitude of IDE's available, however none is absolutely perfect, yet…

• Counterclockwise plugin for Eclipse
• IntelliJ Idea has a plugin La Clojure directly in its repository.
• Clooj is elegant and very lightweight with limited capabilities
• LightTable's Instarepl is just awesome for playing around!
• vim-fireplace here and here recommended together with Redl plugin and vim-sexp
• Other tools at http://dev.clojure.org/display/doc/Clojure+Tools.

Leiningen plugins

• lein-ancient – to check availability of newer versions of used libraries
• lein-kibit – Clojure style checker
