While I personally use Emacs+SLIME to do Clojure hacking this is generally a poor introduction to Clojure for newbies. Clojure is new enough territory without having to fight with your text editor and the idiosyncracies of SLIME (SLIME hasn't even been compatible with swank-clojure since late October). Have you considered trying out NetBeans + Enclojure?
Once you're familiar with Clojure you might later find making the transition to Emacs+SLIME easier. Or not. NetBeans + Enclojure is very good.
