Hi, seeing as you are new and have the ARG, and are looking at PFS I would go something like this.
I would probably take the tail, the scaled skin (keep fire resist), and Maw and claw. Trading out the appropriate stuff. The tail is just for utility, hold a potion, or get a back up weapon. Skin is for the armor boost, and Maw for a bite atk so you still threaten with a bow held.
Stats, str 14, dex 16 (+2 racial=18), con 12, int 10 (+2 = 12), wis 13, cha 10 (-2 =8)
Feat point blank shot, ftr bonus feat precise shot. Take rapid or multishot at third. Then deadly aim.
Traits, ftr of society, and something of your choice maybe reactionary.
This would be a good basic ftr archer. At first level maybe use a sling or thrown weapon, until you can afford a composite bow for your str. Get the best armor your dex will allow, and a basic back up weapon, club to start, then a cold iron morning star.
You will have a good initiative, good accuracy, some skills, and since you are ranged reasonable hit points. You should also have a pretty great AC.
Good luck
