Welcome to the Q&A Forum

Hi Michael It looks like everyone here pretty much has you covered. I also wanted to point you to this resource I did for Moz on setting up WordPress for SEO: http://moz.com/blog/setup-wordpress-for-seo-success In general, I'd agree with noindexing tags. You can index categories, but this won't result in overlapping content as long as you put posts in just 2-3 categories each.

Michael, Philip is on the dot mass footer linking was an SEO trick of the past that does not benefit much in terms of an SEO boost. If its messy clean it up. Leave it ONLY if it makes sense from a user experience, and so optimize for a real human person as he would browsing the lower part of your site. Hope this helps
