No, it is everything. Alpha and G are critical to life, and are universals through-out the universe. They dictate whether stars are possible, or molecules. There is plenty of fine-tuning before we even get to the stage of asking what is needed to get a decent planet somewhere.
But the universe has to come out in some way or other and do we know that other conditions would allow for intelligent life other than our own? If all the conditions up to life but short of intelligence were in place then would the fine tuning arguement still hold?
As Victor Stegner put it "The universe is not fine tuned for humanity. Humanity is fine tuned for the universe."
Why does alpha have its value? If it did not, there would be no observers - fine tuned. What has caused alpha to take this value? We don't know... yet.
Perhaps you could outline the arguements pro and con in the cosmological community? I would find this fascinating.
