How to enable autocomplete for Python class, module site-packages

[Tính Trương Xuân]

   Hello,
I happen to develop Python related project and I select Emacs as my editor. I have installed Emacs 23 on my Fedora 10 machine with the following extension:
- CEDET 1.0pre4
- ECB 2.32
- Pymacs-0.24_beta1

- rope-0.9.1
- ropemacs-0.6
- Python mode (from https://launchpad.net/python-mode/)
But I don't know how to setup Emacs to have "intellisense" for libraries in site-packages of python. Here is my .emacs file:
;; .emacs

;;; uncomment this line to disable loading of "default.el" at startup
;; (setq inhibit-default-init t)

;; enable visual feedback on selections
(setq transient-mark-mode t)

;; default to better frame titles
(setq frame-title-format
      (concat  "%b - emacs@" (system-name)))

;; default to unified diffs
(setq diff-switches "-u")

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; Beginning of my customization
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;; Add our site-lisp to the load-path
(setq load-path (cons "~/.emacs.d" load-path))
(progn (cd "~/.emacs.d") (normal-top-level-add-subdirs-to-load-path))


;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; Common stuff
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;;Removed for readability

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; CEDET stuff
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(load-library "cedet-stuff")

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; ECB stuff
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(load-library "ecb-stuff")

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; Python stuff
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(load-library "python-stuff")

Here is the cedet-stuff.el:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; CEDET
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(load-file "~/.emacs.d/cedet-1.0pre4/common/cedet.el")
;;make all the 'semantic.cache' files go somewhere sane
(setq semanticdb-default-save-directory "~/emacs-meta/semantic.cache/")
;; Enabling various SEMANTIC minor modes.  See semantic/INSTALL for more ideas.
;; Select one of the following
;(semantic-load-enable-code-helpers)
;; (semantic-load-enable-guady-code-helpers)
;; (semantic-load-enable-excessive-code-helpers)
;; Enable this if you develop in semantic, or develop grammars
;; (semantic-load-enable-semantic-debugging-helpers)


Here is the ecb-stuff.el:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; ECB
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; load ECB
(require 'ecb)
(require 'ecb-autoloads)

;; Disable update version check
(setq ecb-version-check nil)

;; Filter unwanted source file
(setq ecb-source-file-regexps (quote ((".*" ("\\(^\\(\\.\\|#\\)\\|\\(~$\\|\\.\\(pyc\\|elc\\|obj\\|o\\|class\\|lib\\|dll\\|a\\|so\\|cache\\)$\\)\\)") ("^\\.\\(emacs\\|gnus\\)$")))))


;;Turn off Tip of the day
(setq ecb-tip-of-the-day nil)

;; Set the layout
(setq ecb-layout-name "left14")

;; Show the source file under the directories
(setq ecb-show-sources-in-directories-buffer '("left7" "left13" "left14" "left15"))

;; Set the left-click mouse button to collapse directory in directory buffer
(setq ecb-primary-secondary-mouse-buttons (quote mouse-1--C-mouse-1))

;; Turn on semantic
(setq semantic-load-turn-everything-on t)
(require 'semantic-load)

Here is the python-stuff.el:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; Python mode customization
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Python mode
(setq auto-mode-alist (cons '("\\.py$" . python-mode) auto-mode-alist))
(setq interpreter-mode-alist (cons '("python" . python-mode)
                                       interpreter-mode-alist))
(autoload 'python-mode "python-mode" "Python editing mode." t)


;; setup pymacs
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)
;;(eval-after-load "pymacs"
;;  '(add-to-list 'pymacs-load-path YOUR-PYMACS-DIRECTORY"))

(pymacs-load "ropemacs" "rope-")
(setq ropemacs-enable-autoimport t)

Emacs run just fine with all the above extensions. What should I do to make "intellisense" for modules, classes, methods in site-packages of Python?

Many thanks.
