Most parking companies use a Google feed and Google thinks it knows better than you what the keywords should be for any given domain. So, some parking companies don't allow you to set keywords any longer, and those that still do, are unlikely to change the keywords that Google use for the search. They might do in an extreme case, but usually you need to get your parking provider to contact Google for them to change the keywords. This can take weeks/months. Even if they agree to the change. So I wouldn't waste my time setting keywords. I think the other SEO stuff like titles/metatags are mostly important for SEO on pages with actual content. Since by definition, a parking page has no content, so won't rank in the SERPS, I can't see what value they add to a parked page. I'd like to hear any others opinions about my thoughts. Does Google even look at the title before it serves up the ads?
