If a food has more unsaturated fats than saturated and trans fats, does the unsaturated cancel out the effects of the saturated and trans?

NO!!!: First of all, there is good reason to question whether saturated fats are actually unhealthy- see http://www.Bmj.Com/content/347/bmj.F6340 however, trans fats are among the most toxic foods one can eat and a major cause of heart disease- see http://bit.Ly/1era8lt ; http://bit.Ly/13o0nkq no amount of healthy fats can "cancel out" the incredible toxicity caused by trans fats.
