I highly doubt the amendments of the Constitution are going to replaced with the Bible and children start being taught that the Earth is 6,000 years old if Palin becomes President (and that's a big IF!).
Presidents can't just amend the Constitution at their will, and we have that big body known as the Congress, which stalled President Obama for over a year in getting his healthcare bill passed, and that was with a Democratic majority in both the House and the Senate. Palin likely wouldn't have a Republican majority in both the House and the Senate as president, but even if she did, I highly doubt all Republicans would go along with trying to impose something like creationism into the public education system (and that's assuming that even would be a goal of Palin's, considering Palin, being a limited government Republican, would likely not even want the federal government to be messing with education most likely (most conservatives see it as a states issue)).
Some quick research shows Palin is okay with the teaching of evolution in schools, but doesn't want it to be part of the curriculum, and would not push for school boards to make it part of the curriculum. But she encourages it be brought up and discussed and is okay with it personally. She also has said she believes parents should have ultimate say over what their child is taught.
Here is a link to quotes she has made on the subject:

As for qualification, I'd say she will need to show she understands the issues.

Did he quit politics to sign a book deal, get a tv commentary deal, and a reality tv series before running?
I wouldn't say Palin "quit," so much as was forced out. She was unable to govern, and personally liable financially for all the lawsuits coming against her. IMO she did the right thing stepping down, both for herself and the people of Alaska (wouldn't have made much sense to risk personal bankruptcy and not even be able to continue governing). If she runs though, her resigning the Governorship of Alaska will probably sort of be to her what the whole Reverand Wright issue was to Obama (critics will harp on it constantly, supporters will be okay with it).
