I did a little reading on the subject, and it does appear that there are a few spring training statistics that carry some value. Prospects Live suggested that maximum exit velocity for hitters is useful and that pitch characteristics (pitch velocity, spin rate, break etc.) are useful for pitchers.

There is a study posted on the economist that argues that spring training stats do have utility despite their inherent noisiness. This appears to be the study that shows that walk and strikeout rates are useful, as is isolated power numbers. Unfortunately it's locked behind a paywall so I wasn't able to read through the entire study vs perusing a summary on ESPN.com.
