Books - any of the intro Clojure books, they're all good. I prefer the OReilly one but I think it's really a matter of preferred style.

Online - Clojure for the Brave and True, Clojure From the Ground Up are great series. Or try the ClojureBridge curriculum https://github.com/ClojureBridge/curriculum.

Practice problems - 4clojure, exercism.io, clojure koans

Editors - if you want to focus on Clojure not an editor, I'd suggest Nightcode or Light Table. If you like IDEs I'd recommend IntelliJ w/ Cursive or Eclipse Counterclockwise. If you already use Emacs, use CIDER. If you already use Vim, use Fireplace.

Also, there are many great videos online - try https://www.youtube.com/user/ClojureTV or http://www.infoq.com/Clojure/presentations/

#clojure is your best online resource tbh.
