Precious shots, rapid fire and massive critical should be maxed, same for main bow skill. Kick trap and fast could be at lvl 1 only, up to you. Depending on difficulty you should get body development at 2 or 3, for me 2 was enough.
I don't remember exactly all skills, it's few years ago I played that build.
I like Stab Rogues the best in this game. I use a very concentrated build to maximize damage potential and high AC/HP because you have to tank Ark. My mental stats are high for the final encounter in Ark and you can see my base selection of advanced skills.
