The "winning combination", isn't that what all webmasters are after??
SEO is an ever evolving "game", so if you want to keep ahead of your competitors you'll need to be updated on the latest SE algorithm changes etc at all times and the best place to do so IMO are at SEO specific forums..
One great source for SEO knowledge that I can recommend is Aaron Wall's SEOBOOK
