Set one of the 580EX flashes to Group A and the other to Group B. Make sure both are in ETTL mode and set as slaves. On the ST-E2, turn on ratio by pressing the RATIO button. Then set the ratio by pressing the < or tne > key. The first number in the ratio is for the Group A flash and the 2nd number is for the Group B flash. So, for example, if you want your main light (Group A in your example) to be 2 stops brighter than the fill light, set the ratio to 4:1. Note that the ratios on the ST-E2 are given in light intensities, not stops.
