For IDEs, I really like IntelliJ + the La Clojure plugin. Many of my coworkers us Emacs + Swank/SLIME. I'm not an emacs user and don't know much about that setup, but it's a very popular setup.
A book that I liked a lot is Clojure in Action (http://www.amazon.com/Clojure-Action-Amit-Rathore/dp/1935182...). I've also heard that The Joy of Clojure is excellent, but it's more appropriate after you're already comfortable with Clojure.
As for online resources, I've found https://github.com/functional-koans/clojure-koans to be very useful. You can clone the project, which consists of a lot of "fill-in-the-blank" unit tests. The tests are designed to teach you the common functions and data structures available in Clojure.
Well my apologies for not immediately understanding your specific situation... I can assure you I meant it as a kind suggestion.
Perhaps you could look at Clojure In Action? It's supposed to be a pragmatic introduction for people with some existing programming experience. From the Amazon page, "is a hands-on tutorial for the working programmer who has written code in a language like Java or Ruby, but has no prior experience with Lisp."
