Do keywords matter that much anymore in the meta? I wasn't sure.
Probably not, since Google creates their own, comprehensive list of keywords based on the relative occurance in your page text. These are the keywords that will actually be used for positioning in search results.
The <meta> keyword list may, instead, be used by Google as an "honesty test" of your site. If the list contains words that do not exist in your page text, the ranking will be penalized accordingly.
In my experience, links to your site from elsewhere can improve your search position significantly, but only if they are from "quality sites" as per Google's definition. If the links appear to originate from a "link farm", your site will be penalized.
