Answer 1

Turn on delete-selection-mode. Then select the text to replace. Then hit C-y. With delete-selection-mode enabled, you just type to replace selected text, as is usual outside Emacs. And C-y also replaces it.

Answer 2

You can also use defadvice. Then this will only work when overwrite-mode is on:

(defadvice yank (before yank-if-overwrite)
  (if (bound-and-true-p overwrite-mode)
      (delete-char (length (current-kill 0))))
  )
(ad-activate 'yank)

Answer 3

Here:

(defun crazy-yank ()
  (interactive)
  (delete-char (length (current-kill 0)))
  (yank))

(global-set-key (kbd "C-M-y") 'crazy-yank)
