So, in theory you should be able to use YPN as alternate ads for AS, but you have to be sure that there's only one ad unit on that page, or you take the chance that one AS ad will show, but the other one will show the alternate. That happens frequently, especially on brand-new pages.
Never show any ads with Adsense on the same page no matter what.
This is definitley incorrect. Lots of people show other ads on the same page with Adsense ads. These other ads, however, may not be contextual (like YPN, for example), and may not look like Google Adsense ads.
An example of an allowable ad on the same page with Adsense are Associate product ads, like from Amazon.
