Questing is the best way. Not the fastest but you will get the extra skill points and collect the shards. Craglorn grinding is by far the fastest, but at vr1, I don't think you will be welcome in many grind groups due to your low level, not to mention you will die a lot. Some do all the dolmens and world bosses in each level, but good luck finding a group. Google grind spots if that is your thing, each zone has some, but I've never tried.
