If you want to stick with Emacs and mzscheme, you can use
scheme-complete (compatible with any scheme mode):

  http://synthcode.com/emacs/scheme-complete.el.gz

It has both intelligent tab completion and eldoc support (showing
a brief docstring in the minibuffer).  In fact, it's much smarter than
slime because it recognizes the current lexical environment.
Given the following:

  (letrec ((foo (lambda (a b) x)))
    (foo

it will show "(foo a b)" in the minibuffer.
