In addition to your extensive listing of unique data
collected, there's an almost endless list of possibilities
for tracking. For instance, simple web bug images
can help ID by allowing 1st-party cookies to be set
by tracking companies. There's even a trick of using
script with the DOM to check the color of links in
the page, thereby telling the server which linked
pages you've visited. (Though notably, few of these
tracking methods can be used without script.)

Time and again it's been demonstrated that there's
no such thing as anonymous data. That, after all, is
the whole point of data collection in the age of computers.
Before computers you might give personal info to a
local store but it was kept in a file cabinet and only used
to deal with you as a customer. Today that same info
can be distributed and analyzed instantaneously.

A company like Google would be thwarting themselves
if they didn't personally identify people. They would
actually need a complex system in place to avoid
making the connections that their business depends on.

The page I linked the other day details some of
the simplest personal tracking that can be done
even by someone with no expertise, just by using
Google tools and thereby letting Google spy on
your visitors:
