Your team is defintely one of hte best in the league (Vlad, Bonds, Hallaway and Wook? whoa), but it's not completetly loaded. Kearns isn't a lock to be great, Rivera will probably be solid but can get hurt and after them, Zito is your only good pitcher.
Your bench is weak too (Klesko, Encarnaccion and the pitchers). You may win your league, but it wont be as lobsided as you may think, especially if someone gets hurt.
