Eeks. None of the above masks your IP which Google gets and matches with your logged in sessions so unless you know of a way to block your IP in a reliable way too it's an effort in futility... and IP is only one of several other tracking methods.
F.Y.I The G+ button at the bottom of this page just recorded your IP. If you have EVER logged into adsense, gmail etc from that IP before Google knows you've been here, and exactly who you are. You can't hide and even if you try you still stick out like a sore thumb for being that guy who's built a unique browser that pings off 'that' network etc.
If you somehow get around all of the above(good luck with that) you are still not anonymous because your internet provider is under legal order to record your every internet action. You can make it harder to be watched, but not much. Using a smart phone or wireless access point? Forget about it, these have even more layers of recording going on.
My suggestion: don't get paranoid. Be knowledgeable about your surroundings but, like a walk in the park, know that you are not private by any means. My only hope is that writing posts like this doesn't land me on some watch list but even if it does... having nothing to hide is the best way to live.
