Just wanna point out, the OP is useing an archtype (which is not core) nor are some of the animals, so Eye for talent being core or not seems to be a mute point.
Also, as for Eye for Talent, Gorilla could start with an Int of 4, giving it the ability to start wearing armor/using a weapon. In addition, the Roc could have Con 11, making it slightly better combat wise from the get go.
Third point, the Ape could wear an "outfit" like a large cloak, if he is armor trained, even better. As long as no one is looking too closely, he should look like a large hairy guy with a huge sword.
As for when you get your companions, I recommend at 1st and 3rd and 5th, taking boon companion for them at the same time (this way they stay with your Druid level until lvl 7) Yes this means 2 levels later for Natural spell, but it keeps your pets viable longer.
