A web page must contain its popular, relevant keywords. Amounts over 70 of the same keyword or over 5 of the same keyword phrase on a page should be avoided.
Going after keywords that do not reflect your webpages' content is time wasted. What will happen is your site will attract customers who are looking for something other than what you offer. Irrelevant keyword stuffing is a likely engine penalty.
"That's a violation of our Webmaster quality guidelines, specifically the principle of 'Don't deceive your users or present different content to search engines than you display to users.'" - Matt Cutts (@ Google).
One motivation behind updating a site is that SE crawlers use a site's change of content (updates) in criteria for their algorithms. Proof of this was found at Yahoo in the Options > Advanced Search menu. Yahoo no longer gives users this advanced search option, but it is a likely an ongoing factor in engine algorithms.
According to Google's Matt Cutts, engines track amount of changed content, when crawling.

In Windows Internet Explorer, the Favorites Bar, found under View > Toolbars, is a time saver because it lets you go to a link in one click. This bar should span across the top of the browser from left to right and should have links useful in SEO. Each having a small icon with a small description that you have renamed after giving them a right click.
The speed of a site is the webmaster's responsibility.
To make a website fast, Google and I recommend using Page Speed.
The second thing that causes a fast loading page is minimizing the use of images.
The third thing is minimal write-up byte size. So, I would take out all the write-up clutter and blank spaces in your html. Also, the use of tables should be minimized.
