PR has not been such a fundamental part of the algo (compared to how it used to be) for a long long time.
I wouldn't listen to what google tell you.
If you're going for a particular phrase, just examine the #1 sites for the phrase you're going for and work out what it is that puts them there.
99% of the time it's anchor text (in big quantity for competitive terms) and page title.
If you're going for a wider variety of phrases to bring up your money pages in G, then other factors play a role, including PR and the redistribution of that PR throughout your domains pages.
But forget about PR for PR's sake and start thinking about links (and anchor text).
PR is just a natural by-product of having links.
