You can use hooks to make mode based customizations.  In your .emacs you 
would put something like:

(add-hook 'c-mode-hook
        (lambda ()
        (local-set-key (kbd "RET") 'c-indent-new-comment-line)))

(add-hook 'c++mode-hook
        (lambda ()
        (local-set-key (kbd "RET") 'newline-and-comment)

(add-hook 'c-mode-hook
        (lambda ()
        (c-toggle-hungry-state 1)))

Try M-x delete-trailing-whitespace.  The documentations says it deletes 
all trailing whitespace across the current buffer.
