I have also heard (and I don't know how true this is of deleting your webmaster tools from google. Depending on which forum you visit, some say not to give google anymore than they need to have. I have mixed feelings about this myself but both sides definitely have some good points.

Your points have always been in place and should be practiced even before Penguin was implemented. Those key items are critical for good SEO practices and not being penalized.
