The Browser Cleanup question you ask Why is it only giving me the options of Bing or Yahoo! and not Google ?, is an acknowledged problem and is being worked on.
Hopefully, that will be resolved soon - but that doesn't get away from the why is it a default option in the Tools section during installation.
Personally I don't like opt-out choices - I much prefer opt-in and that is why I do a custom install and ensure what I want installed gets installed the others don't.
