It's good to have your keyword in your meta description. Definitely don't stuff it with every single variation of your keyword, but try to at least mention it once. If you don't include your keyword in your meta description, it's more likely that the search engines will look elsewhere on your page for that little snippet of content, and you'll lose the chance to do a quick sales pitch for your site.
you should try to fit your keywords into your title tag (this also helps your click thru rate from the SERPs) and your H1 headings, and probably at least once in the body of your page... but don't stuff it in where it doesn't naturally fit and read well.
If your content is "generic" as you say, then it's really only relevant to generic keywords. You make your job a lot easier (both in terms of ranking AND converting visitors to buyers) if you can create content that is truly relevant to the search term to begin with.
