I don't think you really can 'De-Google-ify' your life.
Think about it, if you visit a site and they're using Google Analytics, you're part of Google data. Same with sites using adwords. Firefox and Google are partners (hence the default Google Search in Firefox). You can avoid hosting your videos on youtube, but are you really not going to watch YouTube videos? Ever??
In the end, though you can cancel your Google Accounts, and not 'actively' use their services, you'd have to block adsense and analytics in your browser, but if you're doing that, you're really harming the site-owner more than google (I suspect).
