At 8 months my son still took 3 naps per day, but by a year he was down to 1. Sometimes I think that they just like to do everything on their own time : )
Try the motrin test - give her some about 45 minutes before her morning nap, and then again before her afternoon nap. If she sleeps better, it's probably because of the teething, and I wouldn't switch around her nap schedule yet. If it doesn't make a difference, she might need to drop down to one nap.
Good luck.
