At first I was considering doing Keyword competitive analysis for each phrase but I don't think that'll be worth it.
Don't be too hasty to shrug off keyword research and competitive analysis. Even just spending an hour in Wordtracker can lead to tons of good information.
For instance, when I used to write for About.com, I'd take about a day each month and head off to Wordtracker to research a specific theme. (Recipe search, music search, shopping search, etc...) I'd then go through and pick out some phrases that got great search traffic and had reasonable levels of competitors. I'd compile my findings into a list.
If there were phrases on the list that I'd written articles about, I'd go back and rework them slightly so that they'd rank well for the phrase. If I didn't have any content on the phrases that were highly searched, I'd file that as a future article idea. Then, the next time I needed to write something but didn't know quite what to write, I could look at my list and say "hey, lyric search type phrases are highly searched and not very competitive, I'd better do some research and write an article on that." It really helped me shape the future of content on the site.
Also, keep in mind when building links that you want to build relevant deep links. In other words, if you've got a great article on 401Ks, see if you can get folks to link straight to it, intead of just to your front page. Building deep links to the content throughout your site can help you far more than just trying to get everyone to link to your front page.
