Google offers a great resource about links: Inbound, outbound, and internal. Worth a read to get back to basics.
And this series of posts tells us what we already knew: Sensible linking makes, um, sense. And at least Google rewards your site for sensible linking.
At least they say they do. I still read stories about "inbound links" that have "no relevancy" to your site are still very valuable, but only Google knows, and they seem to be saying that relevancy does matter.
Proof, as they say, is always in the pudding.
