depending on the size of your studio - but the 17 - 55 should be fine. More then f:2.8 you will not need since anyway you have artificial lights and could adjust the level. In my opinion it is always better to have rather more DOF than less (did you ever try to track with marks which were out of focus...? - no fun!) - so you will stop down anyway. The sweet spot of most lenses is between f: 4 and f: 11 somewhere.
Much more important seems to me to have a proper mattebox with sunshades in order to avoid lens flair from the backlights. This could ruin a greenscreen shot.
