SICP, LISP, AND OTHER NOOB QUESTIONS

So I went to my University's library to pick up the book you /prog/fags consider on the same level christfags regard the bible, SICP. The version they have was printed in 1986.  Should I even bother reading it or should I look for the updated version? 

Also, I started w/ python last semester.  Should I actually use LISP/Scheme(inb4 shitstorm), or try to apply the concepts I learn to python or something else? I am familiar with both emacs and vi and do not rely too much on IDEs, (However, I found IDLE to be great for debugging however.) If lisp/scheme is the way to go, is there any special software I need to/should install in order to start lisp/scheme programming?

oh dude also SICP is available free online

and there's supplementary programming exercises too. some of them are pretty cool, like implementing RSA.
