3 each of Hide, Intimidate, Listen, Move Silently, Spot, and perhaps Swim?
Point Blank Shot, Weapon Finesse? If there's another feat we want, Weapon Finesse could be a bonus. And speaking of attack bonuses, I don't quite see where the +5 comes from for the bite. I get +2 size +3 BAB -1 Str unless we put in finesse.
