| When i had my istD's, i would carry 2 sets of rechargeable and two sets of Lith AA's, minimum.
I shoot a lot of winter scenes here, and i needed to keep the batteries warm or i kept getting the dead battery icon a lot.
The regular AA's found in stores would only power the istD for less than 10 shots, so stay away from those. The Lith's gave me the best bang for the buck.
As far as shooting ice skating(we do a lot of that up here.:-)) I would use the fastest lens available and pan.
