If you're certain its about links I would go about getting the questionable links removed. Did you receive a message in your webmaster account regarding un-natural links? I have heard other webmasters are receiving this message.
I am not a big fan of submitting reconsideration requests. If you do resolve an issue, google seems to detect it pretty quickly and restores rankings automatically. This would probably a last resort type of thing after you have taken many steps to resolve your issues, then you at least have something to show google why you should be reconsidered.
