Regarding the controversy, I don't expect it to make them much worse. They lost a coach with a rotten record, and Strauss is a miles better captain than KP. Absolutely miles better. If the controversy is a distraction, it'll be more than cancelled out by having the, err, best captain in their team as captain.
What is it that makes you think Chris Gayle is more talented than Alastair Cook, or Fidel Edwards more talented than Jimmy Anderson? There's nothing in their respective records to suggest that's the case. Actually, I can barely imagine how much excitement there would be if Cook was West Indian.
West Indies to win the ODIs though.
Also- just to add something- so what if Flintoff gets injured? He'll be replaced by Owais Shah, a top-order batsman who would walk into the West Indian side. What if Sidebottom gets injured? Jimmy Anderson comes in, a superior bowler to everyone the Windies have to choose from bar Taylor. Remember what he did to New Zealand?
Having their star players available will be a massive plus, but if they get injured, England should still have more than enough firepower to win this series.
