the longer you use VI, the harder to switch.

anyway, I can answer some of your question.

of course, we can write a piece of elisp and bind it to some keys. It is a
problem for me that there is no such key to bind.

(defun delete-line()
  (interactive)
  (beginning-of-line)
  (call-interactively 'kill-line))

C-x z or M-x repeat. this is not really same as vi dot command, because
it repeat everything, including next-line. if you want repeat many
times, press C-x z z z z z z z ....

there are many solution for this problem. I've got my own.

I hope you can read chinese. if not, feel free to contact me.

(define-key global-map (kbd "C-3") 'wcy-mark-some-thing-at-point)
(defun wcy-mark-some-thing-at-point()
  (interactive)
  (let* ((from (point))
         (a (mouse-start-end from from 1))
         (start (car a))
         (end (cadr a))
         (goto-point (if (= from start )
                            end 
                       start)))
    (if (or (eq last-command 'wcy-mark-some-thing-at-point)
            (and transient-mark-mode mark-active))
        (progn 
          ;; exchange mark and point
          (goto-char (mark-marker))
          (set-marker (mark-marker) from))
      (push-mark (if (= goto-point start) end start) nil t)
      (when (and (interactive-p) (null transient-mark-mode))
        (goto-char (mark-marker))
        (sit-for 0 500 nil))
      (goto-char goto-point))))

If you are curious about Emacs, it is worth to do that. but you should
change the way you are thinking in VI. Emacs is different way. 
Anyway, both VI and Emacs are a powerful tools, just make it confortable
for you.
