I'd use the acid test in the same book for reference. Feral has been suggested at LA +3, which I agree with. The various anthromorphic builds need to be handled individually and largely redone in terms of LA. The baleen whale for instance is LA +0, just 3 monstrous humanoid HD (Which are pretty good) for +8 Strength, +4 Dexterity, +4 Constitution, +4 Wisdom and +9 natural armor. No thought went into that.
Having not really used the other templates I can't suggest much for them.
