  Does the "all blue" in this galaxy indicate a young galaxy?

  Not necessarily, it may have had a close call with another galaxy and that's why there are starforming clumps. That said, in general spirals are younger galaxies compared with most of the elliptical

  The bar indicates it probably had a smaller galaxy for lunch
