#6 Never believe Google.
I'm sure they rank sites on something close to what is presented in Webmaster Tools. Where they show 404's from a page that's 410.
If the page is 410, then it really doesn't make sense to keep it as part of the link graph, does it? I despise them.
Apologies for the semi-diversion.
