1. I remember looking and finding nothing, so I wrote this myself. Patch as required:

(defun run-buffer (args)
  (interactive "sArguments to script: ")
  (save-buffer)
  (shell-command (concat (buffer-file-name (current-buffer)) " " args)
+))

2. Have a look at my indenting setup:

(defun hagus-perl-indent-setup ()
  (setq cperl-extra-newline-before-brace t)
  (setq cperl-indent-level 4)
  (setq cperl-brace-offset -2)
  (hs-minor-mode)
  (cperl-set-style "linux"))

(add-hook 'cperl-mode-hook 'hagus-perl-indent-setup)

3. let emacs take care of your indentation. it is wise. check what function your backspace is bound to ... you can change that if you want.

4. research the indentation setup. read the source. patch if required.

5. patch the source.

6. use 'align'. Here's something handy I keep around for indenting and aligning a selected block:

(defun indent-and-align (beginning end)
  (interactive "r")
  (save-excursion
    (indent-region beginning end nil)
    (align beginning end)
    ))

7. patch the source.

8. patch the source.
