I second faerie raised merenita, would add the folowing:
+1 gentle gift if you want to interact with animals and mundanes making your natural part better.
+1 book learner would help you get over your lower starting for arts, Please don't forget a good concentration score. You could also use Free study if you think you'll have a vis rich covenant.
+4 or +5 incredible or mythic intelligence.
You can totally forgo formulaic spells by taking -6 poor memory and -4 poor formulaic, but that is kinda harsh, better might be -2 poor formulaic, -4 major deficiency in Perdo (penalized anyway), -1 loose magic, -1 poor student, -1 incomprehensible, -1 hedge mage, or forego the poor formulaic and find some nice -2 flaw to round it out (overconfident for instance).
+1 inventive genius would help you get over your lower starting spells (if you want to go for formulaic spells), note that having spells helps you cast them spontaneously.
Abilities will want concentration to offset your faerie raised merenita, and faerie magic to add bonusses to spont faerie spells, taking some nature related abilities would be fitting, and brawl to fight as a bear
Characteristics should focus on intelligence primarely, but keeping your physical stats up would make your shapeshifted forms more terrifying, and keeping the social skills level would help you not get eaten by the wild, or burned at the stake.
I don't have the book, but I seem to remember that Vim was 2 magnitudes harder, Creo and Perdo one, Muto was two magnitudes easier, and Imaginem one. Being a shapeshifter is easy. This would befit a somewhat wandering character, especially with poor memory.
Help you help yourself with a Talisman and a familiar, you have no spells to make anyway so your lab is empty, and you'll want the bonusses.
