One caution: be very careful about over-doing internal linking. There's a profusion of woes over in the penalty discussions at Google Search attributed to sites that link to every page from every page, i.e., red widgets, blue widgets, green widgets in a navbar on every page.

True, but that just illustrates the difference between organic and artificial, SEO-driven, brute-force crosslinking.

There's a big (and obvious) difference between a Wikipedia article that links to related pages within the text and an e-commerce or thin-affiliate page that links to a hundred other pages through running footers and navigation bars. Using hypertext links to cite related content is the most fundamental principle of the Web, and it's unlikely that Google would ever penalize the legitimate, organic citing of related content--at least on sites that otherwise pass the "sniff test."
