The convention is that Emacs Lisp files are named .el and byte-compiled
Emacs Lisp files are named .elc.  Anything is in your site-lisp
directory is, well, unconventional.

You could move those files to your home directory with the mv or cp and
rm commands, and then inform Emacs like this:

(setq load-path (cons "~" load-path))

You would have to show us what you put in your .emacs file and exactly
what error was reported.

Try this and see if you like it:

(add-hook 'text-mode-hook 'turn-on-auto-fill)

Each buffer is in exactly 1 major mode.  You can turn on additional
minor modes via the major mode's hook variable, e.g. the text-mode-hook
variable and the turn-on-auto-fill function above.

"auto-save" means something specific in Emacs.  What you want to do is
to associate the *scratch* buffer with a file.  Since your .emacs file
is executed in the *scratch* buffer, try this:

(set-visited-file-name "~/.scratch")

M-x ps-print-buffer-with-faces (also available on the File menu bar,
under Postscript Print Buffer).
