how to setup emacs to auto-load slime and other stuff

Hi, I am new to the LISP world and plan to develop on linux using CCL on emacs. I have installed SLIME through quicklisp-slime-helper and made changes to the .emacs.d/init.el file so, that when I do M-x slime in emacs, it brings the CL-USER REPL in emacs. I want to know how I can associate this keychord, so that if I execute emacs from command line in a certain way, then it directly goes to the CL-USER prompt.
